This device is a high-performance positive displacement flowmeter, which is a representative model of our positive displacement flowmeters
with HART communication and auto temperature compensator function in the counting section.
With HART communication, various monitoring and parameter settings are possible. Additionally, by measuring the fluid temperature with an externally connected temperature sensor, it continuously and automatically converts the measured flow temperature to the volumetric flow rate at a reference temperature (e.g., 15°C) for measurement.
●Absence of mechanical reduction gear train combined with special carbon bushings contributes to low pressure loss and long life.
●Thanks to pocketless design, the process fluid is virtually free from stagnation in the measuring chamber beneficial to a broad range of fluids, particularly chemicals and foods.
●The counting section allows for mode switching via touch operation, enabling LCD display of accumulated total, instantaneous flow rate, and reset total.
●External outputs can simultaneously output two systems of signals: accumulated signal (pulses) and instantaneous flow rate signal (analog).
●Lineup includes explosion-proof specifications (pressure-resistant explosion-proof structure).
●We also manufacture models approved for applicable high-pressure gas control law.
●By inserting a temperature sensor (resistance thermometer) connected to the register into the pipeline, accurate flow measurement is achieved while carrying out flowrate correction (volume conversion) of the process fluid to the reference temperature and temperature correction (3α) of the flowmeter body simultaneously.
●Compatible with HART communication, allowing for tasks such as remote verification of measurement values and loop checks.
