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.
1. Constant rotor rotation speed, constant torque, constant flow rate with no pulsation results in low pressure loss and enables extremely
quiet operation with minimum vibration.
2. Less rotor friction of the spiral rotors provides high durability.
3. Large discharge rate per rotation and relatively high rotation speed allows measurement of large volumes even with small nominal size.
4. Simple structure without the need of pilot gears.
5. The counting section allows for mode switching via touch operation, enabling LCD display of accumulated total, instantaneous flow rate,
and reset total.
6. External outputs can simultaneously output two systems of signals: accumulated signal (pulses) and instantaneous flow rate signal (analog).
7. Lineup includes explosion-proof specifications (pressure-resistant explosion-proof structure).
8. We also manufacture models approved for applicable high-pressure gas control law.
9. 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.
10. Compatible with HART communication, allowing for tasks such as remote verification of measurement values and loop checks.
