YZ Type Intelligent Flow Totalizer

YZ Type Intelligent Flow Totalizer

Product Introduction:

YZ type intelligent flow totalizer is a secondary instrument which can be used together with kinds of flow meters. It can not only be used as normal flow integration instrument, but can also realize flow compensation automatically and integration with high accuracy module under the cooperation of pressure& temperature transmitter. It can provide output and control signal to recorder and computer for data collecting and flow regulating. It adopts chip micro process for control which improves stability, reliability and safety. The micro computer technology which is adopted can meet requirements of kinds of primary instrument. It has many functions good universality.

Functional Features：

1. Can calculate volume and flow automatically.

2. Can equipped with micro printer, print accumulative flow manually or automatically. (note when order placed)

3. Can indicate transient flow and accumulative flow at the same time.

4. Can process temperature & pressure compensation automatically.

5. Can output 4~20mA signal according to transient flow for recorder or upper monitor.

6. With power fail safeguard, when re-powered, it can operate automatically and save data for a long time.

7. Can set small flow delete function(when transient flow is less than set value, the flow can not be accumulated to accumulative flow ).

8. Can set high & low limit for transient flow and output alarm and control signal.
