●Scope of application
JG-908 Intelligent Flow Totalizer with a variety of flow sensors or transmitters, temperature sensors or transmitters and pressure transmitters used in conjunction with intelligent flow totalizer can be of various liquids, steam, natural gas, the general gas Flow parameters were measured showed a cumulative basis, alarm control, transmission output, data acquisition and communication。
●Features
Intelligent Flow Totalizer full range of automatic temperature and pressure compensation operations, compensation arbitrarily set
Linear integrator, integrating prescribing any set
Instantaneous flow, cumulative flow, temperature, pressure, multiple parameter display
Resection of small-signal functions, the optional removal of 0-5% range
Intelligent Flow Totalizer cumulative flow value can be cleared through the panel buttons, clear operation can lock
Power-down protection, the cumulative flow rate-up time greater than 5 years, all the settings after power off permanently
Intelligent Flow Totalizer advanced modular structure, with a powerful instrument chip, feature set, the system is very easy to upgrade
