Product features
Large measuring range for pipe diameter DN15-2000mm pipe flow measurement
High measurement accuracy, plug-in and pipe accuracy can be as high as 1.
High reliability, low voltage, multi-pulse emission circuit, high measurement accuracy, service life and reliability greatly improved.
Strong anti-jamming ability, the use of double-balanced signal differential transmission, reception circuit, can resist frequency conversion, high voltage and other strong interference.
Powerful memory function, can remember the first 10 years of cumulative flow, can remember the first 64 times on, power off time and flow, automatic ally memory of the first 32 days of the flow meter is normal working state.
Transmission distance is far, network ingress convenient, RS485 supports wireless networking, with GPRS module to achieve wireless transmission.
Support for thermal measurement, mating temperature sensor for temperature measurement
Plug-in ultrasonic flow (thermal) gauge
Installation without interruption, no pressure loss, mated plug-in temperature sensor to measure temperature for thermal metering
Peripheral ultrasonic flow (hot) gauge
Installation without interruption, no pressure loss, mated external paste temperature sensor to measure temperature, for thermal metering
Piped ultrasonic flow (thermal) gauge
Installation requires a cut-off, no pressure loss, highest measurement accuracy, and a mating plug-in temperature sensor that measures temperature for thermal metering
