ZK-XMJA intelligent flow totalizer is used with various flow sensors or transmitters, temperature sensors or transmitters and pressure transmitters. The intelligent flow totalizer can be used for various liquids, steam, natural gas, general gas, etc. The flow parameters are used for measurement display, cumulative calculation, alarm control, transmission output, data acquisition and communication.
â—Features
Intelligent flow totalizer full range of automatic temperature and pressure compensation calculation, compensation mode arbitrarily set linear total calculation, open square calculation, arbitrary setting instantaneous flow, cumulative flow, temperature, pressure, various parameters, display small signal cutting function, cutting range The 0-5% optional cumulative flow value can be cleared by the panel button. The clear operation can lock the power protection function. The accumulated flow value is reduced for more than 5 years. All the set values ​​are permanently maintained after the power is turned off. Structure, with powerful instrument chip, functional combination, system upgrade is very convenient
