Gas turbine flowmeter is mainly used for flow measurement of medium fluids such as air, nitrogen, oxygen, hydrogen, biogas, natural gas, and steam in industrial pipelines. When measuring the volumetric flow rate in a working condition, it is hardly affected by parameters such as fluid density, pressure, temperature, and viscosity. Impact. No moving mechanical parts, so high reliability and low maintenance. There are analog standard signal and digital pulse signal output, which is easy to use with digital systems such as computers. The instrument parameters can be stable for a long time.

The instrument parameters can be stable for a long time. The gas vortex flowmeter uses a piezo-electric stress sensor with high reliability and can operate in the operating temperature range of -20°C to 250°C. Is a more advanced and ideal flow meter.
The pulse frequency signal output by the gas vortex flowmeter is not affected by changes in fluid properties and composition, that is, the meter factor is only related to the shape and size of the vortex generating body and the pipe within a certain range of Reynolds number. However, as the flowmeter needs to detect the mass flow in the material balance and energy metering, the output signal of the flowmeter should monitor the volume flow and the fluid density at the same time, and the fluid properties and components have a direct impact on the flowmeter.
The gas vortex flowmeter is a new type of flowmeter for measuring the fluid flow of a closed pipe according to the Karmen vortex principle. Because of its good media adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. With temperature and pressure sensors, it can measure standard volume flow and mass flow, which is throttling. Ideal alternative to flowmeters. Gas vortex flowmeter For ease of use, the battery-powered local display gas vortex flowmeter uses a micro-power high-tech, using lithium battery power can be continuously running for more than one year, saving cable and display instrument purchase and installation costs, Instantaneous flow, accumulated flow, etc. can be displayed on site. The temperature compensated integrated vortex flowmeter also has a temperature sensor, which can directly measure the temperature of the saturated steam and calculate the pressure to show the mass flow of saturated steam. The temperature and pressure compensation integrated type is equipped with a temperature and pressure sensor. The gas flow measurement can directly measure the temperature and pressure of the gas medium, thereby displaying the standard volumetric flow rate of the gas.
1. Gas vortex flowmeter wiring considerations - Use a complete cable as much as possible. - Keep away from sources of electrical noise (such as high-power transformers, motors, and strong power cables) as much as possible, and avoid parallel wiring with power supply lines. -- It is recommended to use non-soldered clamping lugs on the ends of thick wires. - For waterproof and mechanical damage, it is better to put the cable into the metal conduit, but no high-power transmission cable is allowed in the same conduit. (The maximum power of one transmission cable is greater than the minimum power of the signal cable of the flowmeter. At 10 times, the two cannot be installed in the same catheter. - For areas where there is a strong external magnetic field, the axis of the detection device should be perpendicular to the direction of the magnetic flux of the external magnetic field, or the flow sensor or external magnetic source should be shielded with a high magnetic permeability material. - The connection of explosion-proof turbine flow sensor cables must strictly comply with the relevant standards for explosion-proof amplifiers.
2, gas vortex flowmeter grounding problem - shielded wire can only be grounded at one end, it is best to display instrumentation grounding. - Grounding should be good and reliable, explosion-proof grounding resistance needs to be less than 10Ω.
