Clamp-on ultrasonic flow measurement for steam

World's first clamp-on saturated steam ultrasonic flowmeter

Clamp-on saturated steam ultrasonic flowmeter capable of measuring steam flow without the need to cut piping.

It was previously difficult to measure the steam flow used in factories in various industrial sectors, but this flowmeter can now be installed even when the equipment is in operation.

Measure the steam flow with precision thanks to a new noise reduction technology, whatever the pressure (from 0.1 MPa (G)) and temperature (up to 180 ° C).

Characteristics of the ultrasonic flowmeter for steam

Characteristics :

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 pressure and temperature input.

Various communication functions
The flowmeter is equipped with communication functions such as RS-485 (Modbus specification) and Ethernet (under development), which is capable of carrying out self-diagnosis as an IoT terminal device, and features a remote diagnosis function.
