Product Introduction
The steam vortex flowmeter is a new type flow meter with international advanced level, which is developed based on the principle of Karman Vortex vortex principle. The vortex flow sensor has been widely used in various fields because it has the advantages that other flowmeters cannot have .At the same time, the vortex water flow meter is applicable to measuring the mass flow and volume flow of superheated steam, saturated steam, compressed air, general gas, water and liquid.
Product Features
Simple and firm structure, convenient installation and maintenance. There is no need for impulse piping and three valve manifold to reduce leakage, blockage and freezing. The measuring element has simple structure, reliable performance and long service life.
The accuracy of the steam vortex flow meter is relatively high, generally ± (1 ～ 1.5)% R.
Display the flow value and cumulative flow value at the same time, without switching in turn.
The overall structure design is reasonable, the dynamic measurement range is wide, and the pressure loss is small

Production Line
2. The steam vortex flow meter is not in contact with the medium, with stable quality and strong durability. The vortex flow sensor is usually installed separately from the eddy current, and the high-temperature piezoelectric effect seal does not contact the measured medium in the detection probe. Therefore, the steam vortex flowmeter has the characteristics of simple structure, good general performance and high stability.
3. The vortex flow sensor is widely used, can be used for steam, gas and water.
