Flow speed range
The flowmeter can measure flow velocities from 0 to ±50 m/s, covering a wide range of industrial applications.
Accuracy
For flow velocities of 10 m/s or less: ±0.3 m/s.
For flow velocities from 10 to 30 m/s: ±3% of velocity.
For flow velocities above 30 to 50 m/s: ±5% of velocity.
Piping and Pipe Characteristics
A pipe length of 20 D or more upstream and 10 D or more downstream is recommended to ensure stable, accurate measurement. The flowmeter is compatible with carbon steel and stainless steel pipes, offering installation flexibility for nominal diameters (DN) of 50, 65, 80, and 100. The flowmeter is suitable for pipe thicknesses from 2.8 to 3.9 mm, enabling efficient installation in a variety of configurations.
Fluid conditions
The flowmeter can operate in a temperature range from 120 to 180°C, ensuring stable performance even under varying thermal conditions. In terms of fluid pressure, the flowmeter adapts to the pressure conditions commonly encountered in industrial applications and supports a pressure range from 1 bar to 9 bar.
Environmental Protection
The flowmeter is IP67-rated with connectors fitted, guaranteeing protection against moisture ingress and splashes.
Inputs and outputs
Inputs: Input current (4 to 20 mA DC) ×1, Input temperature (pt100) ×1 (optional).
Outputs: Output current (4 to 20 mA DC) ×1, Total output pulse ×1, Contact output ×1.
Mass Flow Conversion
Mass flow conversion is performed by taking into account the fixed value input (density), the temperature input, and the pressure input.
Connectivity
An RS-485 option is available for easy integration into control and monitoring systems.
Food/Consumption
The flowmeter operates from a power supply of 100 to 240 V AC, with a consumption of 20 VA.
Environmental conditions
The flowmeter can operate in ambient conditions ranging from -20 to +60°C, with an ambient humidity of 95% RH or less. The flowmeter is equipped with a Class D earth connection, with an earth resistance of 100Ω or less, ensuring reliable isolation.
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.
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.
Easy operation and multilingual display The following languages are supported for display: Japanese (Katakana), English, German, French, Spanish.
