Wall Mounted MHC3000B Ultrasonic Flowmeter MHC-3000B+L2
Ultrasonic flowmeter - fixed wall mounted for a variety of long-term online measurement of the liquid, the host and the sensor separately installed, the sensor installed in the need to measure the pipeline, the host and the sensor with ultrasonic flowmeter dedicated cable connection, is currently the most widely used ultrasonic Flowmeter.
Temperature sensor, achieving hot (cold) metering function, the amount of hot (cold) for real-time monitoring.
Features:
1.High reliability: the use of low-voltage multi-pulse balanced transmission circuit, measurement accuracy, service life and high reliability
2.Wide range of measurement: the use of different types of sensors, can achieve caliber DN15 ~ DN6000mm pipe flow measurement
3.Data interface: RS485 serial interface, through the PC computer to upgrade traffic, support MODBUS protocol
4.Anti-interference ability: the use of dual-balanced signal differential transmission, receiving circuit, effectively resist the inverter, TV tower, high voltage lines and other strong interference
5.Powerful memory function: automatic memory before 128 days, the first 10 years of accumulated calories and traffic, the cumulative date and so on can be read through the MODBUS protocol
6.Heat measurement: with the temperature sensor, can be achieved heat (cold) measurement
