Model TUR-200D Turbine Flowmeter

Transcription

1 General Specifications Model TUR-200D Turbine Flowmeter Liquid flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical signal is generated in the pickup coil. This signal is converted into engineering units (liters, cubic meters, gallons etc.) on the local display where is applicable. Optional accessory modules can be used to transmit the signal to other equipment. Upon receipt, examine your meter for visible damage. The turbine is a precision measuring instrument and should be handled carefully. Remove the protective plugs and caps for a thorough inspection. Make sure the turbine flow model meets your specific needs. For your future reference, it might be useful to record this information on nameplate in the manual in case it becomes unreadable on the turbine. Refer to the nameplate for your customized product's specification. - High Stability - Good Repeatability - Convenient Installation / Maintenance - Compact Structure Design

2 Preface TUR Series Turbine Flow Meter will be well configured and tested before leaving the factory. This manual will assist you in installing, using and maintaining your turbine flow meter. It is your responsibility to make sure that all operators have access to adequate instructions about safe operating and maintenance procedure. Warning For your safety, review the major warnings and cautions below before operating your equipment. Sr. Description 1 Use only fluids that are compatible with the housing material and wetted components of your turbine. 2 When measuring flammable liquids, observe precautions against fire or explosion. 3 When handling hazardous liquids, always follow the liquid manufacture's safety precautions. 4 When working in hazardous environments, always exercise appropriate safety precautions. 5 During turbine removal, liquid may spill. Follow the liquid manufacture's safety precautions for cleaning up of minor spills. 6 Do not blow compressed air through the turbine. 7 Handle the rotor carefully. Even small scratches or nicks can affect accuracy. 8 When tightening the turbine, use a wrench only on the wrench flats. 9 For best results, calibrate the meter at least 1 time per year.

3 Working Principle When measured liquid flows through the sensor, impellers rotate by acting force of the liquid, the rotation of impellers makes that reluctance of detection device is in cyclic variation, so that the pulse signals generated by detecting coil are sent to show on display instrument after being amplified by the amplifier. Within the measuring range, the output pulse frequency of the sensor is directly proportional to the volume flow. This ratio is the instrument coefficient which is indicated as K. Where: f- output signal frequency of the sensor (Hz); Q- volume flow passing through the sensor (m³ / h or L / h); N- output pulse number of the sensor; V- total volume passing through the sensor (m³ or L). The instrument coefficient of each sensor is given in verification certificate by production units. Set the K value into the corollary display instrument, then volume flow and total volume can be displayed. For the sensors with accuracy not more than 0.5, when measuring the medium with viscosity below m2 / s, the instrument coefficient given in verification certificate is not required for calibration, when measuring the medium with viscosity higher than m2 / s,, carry out calibration by using of real liquid or an alternative solution with corresponding viscosity and use the calibration value as the new instruments coefficient

Intelligent Integrated Turbine Flow Meter 4-digital instantaneous flow display 8-digital totalizer flow display (Resettable) With Explosion Proof (Exd IIBT6) 3-Point Correction and Non-linearity Compensation on K-Factor Basic Type Ex-Proof Type Note: The K-Factor represents the number of output pulses transmitted per cubic meter (Optional: Liter and Gallons) of fluid passing through the turbine meter. Each turbine has a unique K-Factor. However, turbine meters are not functionally consistent throughout the full flow range of the meter. Therefore, correction and non-linearity compensation on K-Factor can enhance accuracy.

11 Installation Mounting-Position Turbine Flow Meters should be installed at the place in compliance with the requirements below: 1 Easy Maintenance 2 No Electromagnetic Interface 3 No Vibration 4 Away from Heat Source Mounting Orientation All turbine flow meters are designed to measure flow in only on direction. The direction is indicated by the arrow on the body Required Length of Straight Runs Flow altering device such as elbows, valves and reducers can affect accuracy. See diagram 1 for typical flow meter system installation. The recommended guidelines are given to enhance accuracy and maximize performance. Distance given here are minimum requirements; double them for desired straight pipe lengths.

12 Installation See diagram 2 for straight pipe length requirement when there is altering device. Noted: Precaution for direct sunshine and rain when the meter is installed outside. Anti-Cavitation Cavitation can be caused by entrained air, and it can seriously damage the rotor on a turbine flow meter. An amount higher than about 100 mg/l of entrained air or gas can produce error. In addition, cavitation can be caused by too little backpressure on the flow meter. For turbine flow meters, it is better to provide a backpressure (downstream pressure of at least 1.25 times the vapor pressure, plus 2 times the pressure drop through the flow meter. See formula 1. Formula 1: P b 1.25xP v + 2x(P in - P out ) Create backpressure by installing a control valve on the downstream side of the meter at the proper distance detailed above.

13 Installation Thread Connections 1. To protect against leakage, seal all threads with an appropriate sealing compound. Make sure the sealing compound does not intrude into the flow path. 2. Make sure the arrow on the outlet is pointed in the direction of the flow. 3. Tighten the turbine onto the fittings. Use a wrench only on wrench flats. Flange Connection For standard products, the flange follows DIN(ISO ) RF (Raised Face). Note: flange can be customized following other criteria. Use a gasket between the meter flange and mating flange. Determine the material of the gasket based on the operating conditions and type of fluid. Note: Do not over tighten the flange bolts. This may cause the gasket to be compressed into the flow stream and may decrease the accuracy of the meter.
