Ranking of Steam Meter and Flow Meter Manufacturers

Ranking of Steam Meter and Flow Meter ManufacturersIt is mainly used for flow measurement of large-diameter gas, liquid, and steam medium fluids in various industries' industrial pipelines. It is characterized by low pressure loss, large range, high accuracy, and is almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can remain stable for a long time. The plug-in vortex flowmeter adopts a piezoelectric stress sensor, which has high reliability and can operate within a temperature range of -20 ℃ to+250 ℃. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively efficient and ideal flow meter..

Ranking of Steam Meter and Flow Meter ManufacturersExplosion proof type, in accordance with the relevant provisions of GB3836-83 "Explosion proof Electrical Equipment for Explosive Environments", with the explosion-proof mark ExdIIBT6.

working principle

According to the standardization organization IS07145 (velocity measurement method for fluid flow measurement at a single point in a closed pipeline with a circular cross-section), a vortex street velocity probe embedded with a piezoelectric crystal is used and inserted into a large-diameter industrial pipeline to convert the Karman vortex frequency into a current or voltage pulse signal proportional to the flow rate, or a 4-20mADC current signal.

For the convenience of use, the battery powered local display vortex flowmeter adopts low-power consumption *, and can operate continuously for more than a year with lithium battery power supply, saving the procurement and installation costs of cables and display instruments. It can display instantaneous flow, cumulative flow, etc. on site. The temperature compensated integrated vortex flowmeter also comes with a temperature sensor, which can directly measure the temperature of saturated steam and calculate the pressure, thereby displaying the mass flow rate of saturated steam. The temperature pressure compensation integrated type is equipped with temperature and pressure sensors, which can directly measure the temperature and pressure of the gas medium for gas flow measurement, thereby displaying the standard volume flow rate of the gas.
