Description
Products Description
Clamp Vortex flowmeter is a volume flowmeter that measures the volume flow rate of gas, steam or liquid, the volume flow rate of the standard condition or the mass flow rate according to the Karman vortex principle. It is mainly used for the flow measurement of industrial pipeline medium fluids, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large range, high accuracy, and is almost not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. There are no moving mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time. Vortex flowmeter adopts piezoelectric stress sensor, high reliability, can work in the operating temperature range of -20℃ ~ +350℃. With analog standard signal and digital pulse signal output, it is easy to use with digital systems such as computers, and is a relatively advanced and ideal measuring instrument.

Features
1. No moving parts, simple structure, easy to install and maintain.
2. Sensor outputs a pulse signal. Its frequency is in linear relation to the measured fluid flow. No drift. Performance is very stable, and has various forms--- pipe-type and inserting type sensors.
3. High precision, normally±1.0% for liquid measuring, ±1.5% for gas measuring.
4. Measuring range is wide. When Reynolds Number is within the range of 2x10^44 ~ 7x10^6, measuring range can be up to 1:20, inserting ratio can be up to 1:25.
5. Pressure loss is small (about 1/4 ~ 1/2 of the orifice flow meter). It is energy-saving flow meter.
6. Using interference elimination circuit and anti-vibration sensor head, it has a certain resistance performance to the environmental vibration.
7. With ultra-low-power micro-processor technology, a 3.6V10AH lithium battery can work more than one year.
8. There are software instruments to correct the coefficients' nonlinearity, and therefore improve the measuring accuracy.
9. Use EEPROM to do power-off protection of the cumulative flow rate, and it can be protected more than 10 years.
10. Inserting vortex flow meter can measure medium with temperature up to +250℃.

FAQ
Q：What medium can be measured using a vortex flowmeter?
A：Vortex flow meters are mainly used for flow measurement of industrial pipeline medium fluids,Vortex flow meters measure the volumetric flow rate, standard volumetric flow rate, or mass flow rate of gases, vapors, or liquids
Q：Can a vortex flow meter be used for chlorine gas?
A： Yes, but a vortex flowmeter made of all tetrafluoro material must be used
Q：Can vortex flow meters measure steam with temperatures over 300 degrees and below 400 degrees?
A：Yes, the vortex flowmeter can withstand a maximum temperature of 400 degrees Celsius.
Q:Vortex flowmeter has fluid flow in the pipeline after being powered on, but no signal output?
A:● Check whether the instrument wiring is correct and whether there is a broken line.
● Check whether the instrument installation direction is correct.
● Check whether the traffic is below the normal flow range.
Q:The flow of fluid in the pipeline is stable and meets the flow requirements, but the output changes too much and is unstable.
A:● May be poor grounding to introduce interference.
● May be the pipeline vibration is too strong to introduce interference.
● It may be that the sensitivity is too low and there is a leakage trigger phenomenon, so improve the sensitivity.
