2 meters and Sight Indicators How flowmeters work: Variable area flowmeters are basically vertical internally tapered tubes mounted with the large end at the top. A float or rotor with an outer diameter slightly less than the minimum diameter of the tube is placed inside the tube. The clearance space between the float and the tube forms an annular passage or orifice. As the tube is tapered, the area of this orifice is larger when the float is near the top than it is when the float is near the bottom. By connecting the tube into a fluid flow line so flow direction is from bottom to top, the float will move upward and be supported at a point where the orifice is just large enough to pass the fluid flowing through the system. Several Forces are involved The precise position of the float within the tube is determined by several forces acting on it. These forces are:. The weight of the float;. The velocity pressure of the flowing fluid multiplied by the area of the float;. Buoyancy of the float (weight of fluid volume displaced by the float);. Viscous aerodynamic or hydrodynamic drag of the fluid on the float. The float s weight acts downward while velocity pressure, buoyancy and drag all act upward on it. Readout and scales By making the tube transparent so that float position can be seen and by providing a scale along side, we may read the float position in terms of numbers on the scale. These scale numbers can be of two types:. Of an arbitrary nature (by themselves they mean nothing, but become meaningful when compared with a calibration curve) or:. They can be precalibrated for direct reading; to show the actual volume flow (in cfm, cc per minute, etc.) of the fluid for which the flowmeter is calibrated. Limiting factors Although the basic relationship outlined above is linear, certain fluid properties tend to modify this relationship. These changes are accentuated where the variable orifice formed between float and tube becomes either very large or very small. For example.. Sonic velocity Where the orifice is particularly large and is combined with a heavy float, velocities of a gas or other fluid through the orifice area can approach sonic velocity. In this velocity range, reflected shock waves cause the float to become unstable, and it will typically hunt from side to side and from top to bottom within the bore. At best, this condition makes it impossible to take a reading, and at worst may even destroy the flowmeter. The addition of flow guides (built into certain Dwyer RateMaster flowmeters) can often improve the stability and performance of the system by channeling the flow into multiple streams that equalize dynamic effects and preventing oscillation of the float. This has the net effect of moving the limit of satisfactory operation upward, and thereby expanding the range and accuracy we can achieve with any given flowmeter tube. Laminar flow In flowmeters where the orifice area is extremely small, the conditions result in smooth flow, or laminar flow. Other factors which contribute to the transition to laminar flow are low velocity (often associated with a lightweight float), low density or specific gravity and high viscosity of the flowing fluid. When laminar flow conditions prevail, a greatly expanded scale is usually required. Meters operating in the laminar flow area are very difficult to manufacture and calibrate to the degree of accuracy usually expected of variable area flowmeters. Turbulent flow Most variable area flowmeters operate in the turbulent flow range which occurs below sonic velocities and above the laminar flow range. In turbulent flow, the flowing fluid particles move in random paths within the stream rather than in violent shock waves as in sonic flow or very smooth parallel paths as in laminar flow. In turbulent flow, variables follow the relationships shown in the curves on Page. These curves are quite accurate for small changes in pressure and specific gravity. For large changes or where a change in viscosity is involved, it is much better to have the flowmeter recalibrated for the specific conditions under which it will be used. Reynolds Numbers Reynolds Numbers are useful in the study of fluid behavior and are quite helpful in separating laminar and turbulent flow. The Reynolds Number of a fluid flow system is described as a dimensionless index. It is equivalent to the diameter of the orifice in feet times the average velocity of the fluid in feet per second times the density of the fluid in pounds per cubic foot divided by the absolute viscosity in pounds per second foot. A system operating with a Reynolds Number of less than 000 is said to be subject to laminar flow, whereas Reynolds Numbers above 000 are clearly in the turbulent flow area. How sight flow indicators work: A sight flow indicator basically consists of a small housing equipped with a glass window which is inserted in a run of pipe to observe the flow of the fluid in the pipe. To enhance the visibility of the flow, a spinner is often incorporated in the indicator. The axis of the spinner is offset from the center of the flow stream so that fluid impinging on the spinner vanes causes it to turn. The spinner also aids in the detection of low flows as well as providing visibility of flow from a distance. In addition, the speed of rotation gives a relative indication of flow velocity. Midwest Sight Indicators are also available with hinged flappers instead of spinners to indicate bidirectional flow. Sight flow indicators can be provided with a single window on the front of the indicator or double windows, one on the front and one on the back of the indicator. Double window units are best when observing the clarity or color of a liquid. Midwest single window units are always equipped with spinners to provide for observation of clear fluid flows at the lowest cost. Vertical tubetype sight flow indicators consist of a clear glass tube, equal to or greater than the diameter of the pipe into which it is inserted, and are utilized to observe high flow rates in vertical pipe runs. No spinners or other type of detection devices are incorporated in these units. As a result, they offer no significant resistance to flow and therefore provide the lowest pressure drop of any type sight flow indicator. Midwest Sight Indicators are available with special materials to meet various applications. Optional materials are available for the sealing gaskets, spinners, and housings or flanges.

39 Introduction to Vane Operated Switches What Are They? A vane operated flow switch is a device which utilizes the force exerted on a vane inserted in a flowing fluid to actuate an electric switch at a predetermined rate of flow. The electric switch may be used to start or stop pumps, open or close valves, actuate a warning lamp, sound an alarm, etc. W.E. Anderson and Dwyer flow switches are suitable for application with a variety of process fluids. The flow switches are available with a wide range of flow actuation points for all standard pipe sizes. Most Anderson switches are explosionproof and UL, CSA approved. How Do They Work? When fluid moving in the indicated direction of flow impinges upon the flow switch vane, the vane swings on the pivot point until the vane stop hits the switch body. This moves the magnet keeper away from the magnet on the inside of the switch body. Without the magnetic attraction provided by the keeper, the switch actuation lever swings by the force of gravity, thus actuating the snap switch. With the cessation or a decrease in flow below the deactuation point, gravity allows the vane to return to a vertical position. The magnet is again attracted to the keeper moving the switch actuation lever and deactuating the snap switch. The switch is therefore deactuated in the no flow condition. The actuation/deactuation points are functions of the area of the vane exposed to liquid flow, the pipe diameter and characteristics of the fluid. and deactuation flow rates are satisfactory. For very low flows, the V6 Low Switch with a field adjustable actuation point is recommended. The V6 Low Switch differs slightly in its operation as increasing flow displaces a piston against a return spring and this movement is magnetically coupled to the switch actuating lever. The operating piston does result in a higher pressure drop than for the standard V6 or V. Actuation/Deactuation Points The V6 and V6 Low switch actuation/deactuation points are fixed to those values given in the specifications. However, the V can be supplied for a wide range of actuation and deactuation points for various fluids and pipe diameters. For a given V vane area, the deactuation flow is approximately 55% of the actuation flow and the actuation flow rate increases with an increase in pipe diameter or a decrease in specific gravity of the fluid. If the actuation/deactuation points offered in the standard VU multi layer vane flow switch do not meet your requirements, include the following information with your order:. Desired actuation and/or deactuation flow rate.. Pipe diameter and schedule.. Type of fluid and. Its specific gravity. Preferably, request an Application Data Sheet, return it to us, and we will fabricate the proper V vane for your application. Maximum PSI Rating Anderson flow switches are rated for maximum operating pressures from 50 psig ( V8) to 000 psig ( V and V6). See Specifications. What is the Dead Band? When the flow switch is actuated by movement of the vane, some of the force required to actuate the switch must be removed before the switch will deactuate. The dead band is the amount of flow that must be removed before the switch deactuates. For a given vane size and/or liquid, the dead band is essentially a function of the mechanical movement of the vane and the switch actuation mechanism. Considerations in Selecting a Switch. Model Selection For the higher flows encountered in pipe sizes of " or larger, The V Switch provides the least resistance to flow (pressure drop) with a wide selection of actuation points. For pipe sizes from " to ", the smaller V6 Switch can be utilized assuming that the specified actuation Installation Install both V and V6 Switches with the index arrow on the switch body pointing in the direction of flow. V models only, must be vertical. The V is installed in a " threadolet welded to the pipe. The shape of the vane will vary, the length being limited by the pipe diameter and the width being limited by the opening of the mounting provided in the pipe. Some V vane configurations may require a threadolet up to " in size. The V6 Switches are supplied with installation tees for plumbing directly in line. 76 VISIT OUR WEBSITES:

40 Typical Switch Applications Air flow switch protects preheater from overheating. Dangerous overheating would occur in this gasfueled air preheater if the blower fails or the air flow is obstructed. To protect against this condition, a Dwyer Model 50 air flow switch wired to the gas supply solenoid valve will close the valve if the air flow fails. A normally closed solenoid valve is specified to provide for failsafe operation of this protective system. Where hazardous ambient conditions exist, a W.E. Anderson Model V Flotect explosion proof flow switch can also be used. In addition, a Mercoid Model M5 temperature switch can be used to monitor preheater temperature. Flotect flow switch shuts down pump when flow stops. When the liquid in this supply tank is exhausted, the W.E. Anderson V6 Flotect switch senses the loss of flow and stops the pump motor, preventing pump cavitation and saving energy. Use of this emergency industrial shower actuates Flotect flow switch which sounds alarm to bring help. In this emergency industrial shower, a V Flotect flow switch has been mounted in the water supply pipe. It will activate either an audible or visual alarm (or both) to summon help when the shower is used by an employee who has been accidentally contaminated by hazardous material. Flotect flow switch protects aircraft deicing equipment. This aircraft deicer saves time and heating fuel by heating only the fluid dispensed, not the entire tank. With the deicing fluid heated by three large heat exchangers operating in parallel, deicing can begin within 90 seconds regardless of ambient temperature. Three Anderson Model V6 flow switches are used to sense adequate flow of deicing fluid through the heat exchanger, one switch on each exchanger. Should fluid flow be interrupted or drop below a safe level, the burner for the affected heat exchanger will shut down. The V6 flow switch is well suited to this application because of its reliability and inherently weatherproof design. CALL TO ORDER: U.S. Phone U.K. Phone (+) (0)96707 Asia Pacific Phone
