Gas vortex flowmeter
TC-ZWJ-2 gas vortex flowmeter is the most ideal substitute for orifice flowmeter. Vortex flowmeter is a new type of internationally advanced flowmeter which is successfully developed based on the principle of Carmen vortex street. Other flowmeters have advantages that have not been achieved. They have developed rapidly since the 1970s. According to relevant data, the proportion of vortex flowmeters in developed countries such as Japan, Europe, and the United States has increased sharply. Dominates future flow meters.
TC-ZWJ-2 gas vortex flowmeter is suitable for measuring the mass flow and volume flow of superheated steam, saturated steam, compressed air and general gases.

Simple and solid structure, no moving parts, high reliability and very reliable long-term operation. Simple installation and convenient maintenance. The detection sensor does not directly contact the measured medium, and has stable performance and long life. The output is a pulse signal proportional to the flow rate, no zero drift, and high accuracy. Wide measurement range and range ratio up to 1:10. The pressure loss is small, the operating cost is low, and it is more energy-saving. Within a certain Reynolds number range, the output signal frequency is not affected by the fluid physical properties and component changes. The meter coefficient is 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. Calibration instrument factor. Wide range of applications, the flow of steam, gas and liquid can be measured. The verification cycle is two years.
TC-ZWJ-2 type gas vortex flowmeter has an inner diameter range of 25-300mm (full tube type), TC-ZWJ-2 type gas vortex flowmeter has an inner diameter range of 350-1200mm (plug-in type), full The accuracy of liquid measurement of tube is 1%, the accuracy of measurement of steam and gas is 1.5%, the accuracy of measurement of plug-in liquid is 2%, the accuracy of measurement of steam and gas is 2.5%, the temperature of the measured medium is -20 ~ 150 ℃, -40 ~ 250 ℃, + 100 ~ 350 ℃ (tube type only), the output signal is three-wire voltage pulse, three-wire 4-20mA, two-wire 4-20mA
Fourth, the basic structure and installation dimensions
The flow meter consists of a meter body, a pillar and an enlarged display device. There are two ways to connect to the pipeline, namely flange mounting and flange connection. Figure 1 shows the flange installation, and Figure 2 shows the flange connection.
