Product details

Dual-channel ultrasonic flowmeter/heat meter is used to measure ultrasonic transmission time through high-precision time digital conversion chip, which can effectively overcome the problems of zero drift and large error in small flow measurement. The flow rate is measured by time difference method. Support a variety of communication methods; It has the advantages of high measurement accuracy, simple operation and stable operation.

The measurement accuracy and reliability of the instrument in complex fluid state are improved effectively by supporting dual channel measurement.

The measuring technology of time difference method is adopted comprehensively to avoid zero drift effectively and improve the measuring accuracy of small flow.

Support RS485 communication, with 4 ~ 20mA transmission, as well as relay switching function, more convenient integration with enterprise energy management system;

The host and probe types are diverse, and can be used together according to the needs of the field, which can meet the installation and measurement of special environments;

Rich interface, easy to use and operate.
