3 The compact Flotect Model L6 Level Switch is designed and built for years of trouble-free service in a wide variety of process liquid level applications. Machined from brass or stainless steel bar stock, the body is leak proof, eliminating the possibility of the process media entering the switch housing. The float level pivoted within the body moves when the process liquid displaces the solid polypropylene or stainless steel float. A magnet on the opposite end of the float level controls a second magnet on the switch actuating lever located in the switch housing. Maintenance is easy since the electrical assembly can be removed for inspection or replacement without removing the entire switch. The stainless steel float lever arm and the polypropylene or stainless steel float are compatible with most process fluids. The Flotect Model L6 is sensitive to level changes of less than 1/2 (12 mm) and is U.L./C.S.A. listed for explosion-proof service - Class I, Groups A, B, C & D and Class II, Groups E, F & G.

11 LEVEL CONTROLS Series RF Level Controls employ radio frequency technology to precisely monitor the level of almost any solid or liquid, completely ignoring product build-up. Probe has no moving parts to fail and a fully adjustable time delay avoids false signals. A low frequency FM signal is continuously emitted within the tank from the 316SS antenna. As the media being monitored nears or covers the probe, a change in capacitance occurs which is sensed by the receiver circuit and converted into on-off switching of a DPDT relay. Each unit is quickly and easily calibrated in the field for unique dielectric constant characteristics of the specific product being controlled. Simply adjust a trim pot inside the control head unit and a bright red LED confirms that the system is calibrated and ready for operation. Once set, these units will operate for years, unaffected by material build-up, even with problem materials like latex paint which can quickly disable most mechanical controls. Standard models are designed for top mounting but a special unit with Teflon sleeve is offered for horizontal mounting. Where greater sensitivity is needed for materials with a 20 or lower dielectric constant, consult Baker about special units with 7/8" diameter probe. A separate control box is typically installed at a convenient location to allow easy changes in wiring, time delay duration, observation of level status, etc. Voltage between control box and probe is only 20 VDC for intrinsically safe operation. A full complement of controls includes four time delay ranges from 0-30 seconds up to 2 hours with separate fine adjust control plus selectable high or low failsafe operation. Dual probe packages include one each of a 12 or 60" or 24 and 60" unit for high/low control. A latching switch enables you to connect the pair for differential operation. The control box card also includes an LED indicator for each system so you always know circuit status no matter how remote the location. Probes are easily trimmed to shorter lengths where required. 414 M2185E Features: RF technology is immune to product build-up Easily adjusted for nearly any solid or liquid in minutes No moving parts in probe for dependability Probe can be any length required - field trimmable Adjustable time delay prevents false signals 20 VDC probe with zenor diode protection of safety ELECTRICAL Power Supply: 110/120 VAC std., user selectable for 220 VAC or 24 VDC Power Consumption: Approx. 5 VA Switch Contacts: DPDT form C contacts, 115 VAC Time Delay: On or Off delay, four ranges adjustable from 0 to 30 seconds, 1 sec. to 2 min., 2 sec. to 16 min. or 15 sec. to 2 hours Connecting Cable: 18 AWG, 3-wire shielded or in metal conduit, to 1000 feet.

Stainless steel probes of various lengths are immersed in the liquid being monitored. One probe (ground sensor) emits a low-level 12V signal into the liquid; the remaining probes act as level sensors. As the liquid contacts each sensor, a circuit is completed, lighting the corresponding LED on the controller display panel. Pumps or valves can then be activated by means of an SPDT relay (2A at 220 VAC). A complete system requires: 1) A controller, with or without alarm 2) A sensor holder 3) One or more packages of sensor probes CONTROLLERS Choose from controllers with or without "over-level" alarms. All controllers have an SPDT relay for use with pumps or valves, and LEDs indicate low level and high level. You can mount all models in a panel cut-out or on a wall, or attach them to a 35 mm DIN rail. Model HI7873 senses water level at some point above the high level and features an additional LED to indicate excessive level. It also has an additional relay (2A at 220 VAC maximum load) to control an optional external alarm. SENSOR HOLDER This unit is basically a black box with 4 threaded openings for the connection of the probes which are used as level sensors. Each transmitter contains a completely resonated amplifier circuit and a 2-wire terminal board. Connections from controller to terminal strip are made from the top of the housing using standard copper wire (not included). Includes mounting bracket that attaches to top or wall of tank. SENSOR PROBES These sensor probes have threaded ends and are made of 316 stainless steel; measure 50 mm in length. Join probes for use in deeper tanks. Cut probes to form shorter sensors as needed. Probes are sold in packs of five -- use one for low level, one for high level, and one for the ground sensor. Models with alarms require a fourth sensor for overflow measurement. The ground sensor has to be the longest and is connected to the COM port.

13 WATER LEVEL METERS The Flat Tape Water Level Meter is ideal for measuring the depth of water in wells, boreholes, and standpipes. It uses a well designed probe attached to a permanently marked polyethylene flat tape cable, fitted on well-balanced reel. The probe is 3/8 in diameter and incorporates an insulating gap between electrodes. When contact is made with static water, the circuit is completed, sending a signal back to the reel which in turn activates a loud buzzer. The cable is two-conductor, steel and copper plated, with a tensile strength of 300 lb. and a tough plastic insulating jacket. Depth indication is provided by numbered tags securely crimped to the cable at intervals of five feet. The high quality storage and winding reel has a convenient carrying handle, a brake, and a sturdy, stand-alone design. Standard controls include a battery test button, on/off switch and an interval sensitivity adjustment.
