Gas turbine flowmeter is mainly used in industrial pipeline in the air, nitrogen, oxygen, hydrogen, methane gas, natural gas, steam medium such as fluid flow measurement, the measurement condition of volume flow is almost not affected by the fluid density, the influence of the parameters such as pressure, temperature, viscosity.
No moving mechanical parts, so high reliability, small amount of maintenance.
There are standard signal simulation and digital pulse signal output, easy with a computer digital systems, such as instrument parameters can long-term stability.
Vortex street flowmeter using piezoelectric stress sensor, high reliability, can be in -
Working temperature of 20 ℃ ~ + 250 ℃ within the scope of work.
Is a kind of comparison, the ideal flow meter.
Gas output pulse frequency of vortex flowmeter signal is not affected by fluid physical properties, and composition change, namely the instrument coefficient in only within a certain range of Reynolds number and swirl through the body and the shape size and so on.
But as flow meter need to be detected in the material balance and energy metering mass flow rate, the flow meter should be monitored at the same time the output signal of the volume flow rate and fluid density, fluid property and has a direct influence on flow metering or components.
Gas vortex street flowmeter is based on the principle of karman vortex closed pipe fluid flow measurement of new type flowmeter.
Medium because of its good adaptability, no compensation can be directly measured temperature and pressure steam, air, gas, water, and the operation condition of the liquid volume flow, temperature, pressure sensor to measure standard conditions and volume flow to mass flow, is the ideal substitute of orifice flowmeter.
Gas vortex flowmeter in order to use convenient, battery-powered local display type vortex flowmeter using micro power consumption of new and high technology, using lithium batteries don't run around more than a year, saving the purchase cost of installation, cable and display instrument to local display instantaneous flow and cumulative flow, etc.
Temperature compensation of a bodily form vortex flowmeter with temperature sensor, can directly measure the temperature of saturated steam and calculate the stress, which shows that the mass flow of saturated steam.
A body temperature pressure compensation with temperature and pressure sensors, used for gas flow measurement can directly measure the temperature and pressure of gas medium, showing the state of the volume of the gas flow.
1, gas wiring considerations - vortex flowmeter
- - - - - -
As far as possible using a complete cable.
- - - - - -
- - - - - -
Should as far as possible away from electrical noise (
Such as high power transformer, electric motor and the power cord)
To avoid parallel to the power the power cord wiring.
- - - - - -
- - - - - -
Suggestions in the end of the thick wire adopts the tin welding clamping lugs.
- - - - - -
- - - - - -
Good for the waterproof and mechanical damage, the cable into metal tube, but shall not be within the same catheter with high power transmission cables, (
A transmission cable transmission power is greater than the flowmeter signal transmission cables of small power 10 times, both cannot be installed on the same catheter)
。
- - - - - -
- - - - - -
The existing strong magnetic field outside the area, should make the axis of the detection device with the outside world vertical or the direction of the magnetic flux of the magnetic field with high permeability material for shielding flow sensor or external magnetic source.
- - - - - -
- - - - - -
Explosion-proof type turbine flow sensor cable connection, must strictly abide by the relevant standards of explosion-proof amplifier.
2, gas grounding problem - vortex flowmeter
- - - - - -
Shielding wire can only be grounded at one end, to display instrument grounding.
- - - - - -
- - - - - -
Grounding should be good and reliable, explosion-proof type grounding resistance should be less than 10 & Omega;
