Features
■Install a temperature sensor in the vortex flowmeter, and take the flow sensor sleeve as a temperature sleeve to isolate the vortex flow and the temperature sensor from the process, thereby ensuring easy verification and replacement.
■Temperature compensation capability of saturated steam, the density is calculated from the process temperature, and the calculated density is used to provide a temperature compensated mass flow.
■Improve the performance in saturated steam, as electronic components compensate for changes in process temperature, thereby improving performance in saturated steam.
■Reduce the installation cost, the multivariable vortex flowmeter do not require an external temperature sensor.
■Equipped with a flow totalizer providing additional functionality, integrating a multivariable vortex flowmeter with a pressure transmitter for full pressure and temperature compensation of superheated steam and various gases.
Product Classification
1、Clamped multivariate vortex flowmeter
No moving parts, long-term stability, simple structure for easy Installation and maintenance, temperature compensated mass flow accuracy: ±2.5% measured value (normal condition) Process temperature accuracy; 1 °C
2、Flanged multivariate vortex flowmeter
Widely used in measurement of standard condition flow rate and mass flow of compressed air, saturated and superheated steam, natural gas and various medium in medium and small pipes.
