HB-908 Intelligent flow integratorDetailed product description：

Scope of application
The JK-908 intelligent flow integrator is used in conjunction with various flow sensors or transmitters, temperature sensors or transmitters, and pressure transmitters. The intelligent flow integrator can measure and display various flow parameters of liquids, steam, natural gas, general gases, etc., accumulate calculations, alarm control, transmission output, data acquisition, and communication.

Features
Intelligent flow integrator with full range automatic temperature and pressure compensation calculation, compensation method can be set arbitrarily
Linear integration and square root integration can be set arbitrarily
Display of multiple parameters including instantaneous flow rate, cumulative flow rate, temperature, and pressure
Small signal resection function, resection range 0-5% optional
The accumulated flow value of the intelligent flow integrator can be reset to zero through the panel buttons, and the reset operation can be locked
Power off protection function, the accumulated flow value can be maintained for more than 5 years after power failure, and all set values will be permanently maintained after power failure
The advanced modular structure of the intelligent flow integrator, combined with powerful instrument chips, makes function combination and system upgrade very convenient
