Characteristics of the ultrasonic flowmeter for steam
High accuracy Steam flow rate can be measured in the 0 to 50 m/s range, and high-precision measurement at ±3.0% of rate (10 to 30 m/s) is possible.
Measurement possible from low pressure (low temperature) Steam flow rate can be measured from a low pressure of 0.1 MPa (G) (temperature: 120°C).
Zero pressure loss No pressure loss,due to mounting externally on pipes.
High-speed calculation The flowmeter is equipped with a high-performance CPU, offering high-speed response of 0.2 seconds.
Mass flow rate conversion Mass flow output is possible by conversion with volume flow and density input. Density can be adjusted by temperature sensor and for pressure transmitter.
