For higher quality accuracy requirements, gas mass flowmeters can be selected for trade settlement. Of course, vortex flowmeters with temperature and pressure compensation can be selected for quality display, and they can also be used for trade settlement. Sanchang Instrument is a professional manufacturer of carbon dioxide flowmeters. It is a professional carbon dioxide flowmeter manufacturer. The price consultation telephone is 0517-86998326. If the lateral vibration is relatively severe, due to the weak anti-interference ability of the vortex street against the lateral vibration, differential pressure is required at this time Type flow meters, such as V-cone flow meters, orifice flow meters, etc.

 The vortex carbon dioxide flowmeter is a new type of carbon dioxide flowmeter developed by using the principle of liquid vibration. It is widely used in the measurement of fluids in petroleum, chemical, metallurgy, papermaking and other industries. The carbon dioxide flowmeter has no moving parts, and has strong reliability and accuracy. High, long life, can accurately measure the instantaneous flow and accumulated flow of liquid in a wide flow range. It is not affected by the temperature, pressure, viscosity and components of the medium, and at the same time it is not blocked, not stuck, not easy to scale, is resistant to high temperature and high pressure, is safe and explosion-proof, and is suitable for harsh environments. The carbon dioxide flowmeter is divided into integrated display and remote transmission display, and can output pulse signals or current signals to connect to the computer.
2. Main features

1. The structure is simple and firm, with no moving parts, high reliability, and very reliable long-term operation.
2. The installation is simple and the maintenance is very convenient.
3. The detection sensor does not directly contact the measured medium, with stable performance and long life.
4. The output is a pulse signal proportional to the flow rate, with no zero drift and high accuracy.
5. The measurement range is wide, and the range ratio can reach 1:10.
6. Within a certain Reynolds number range, the output signal frequency is not affected by the physical properties and composition changes of the fluid. The meter coefficients are only related to the shape and size of the vortex generator. There is no need to compensate when measuring the volume flow of the fluid, and there is generally no need to renew after changing accessories. Calibration instrument factor.
