EFM-100 Volume Corrector

Overview
EFM-100 volume corrector is an intelligent secondary instrument coming with the gas flowmeter. It adopts a high-precision digital temperature
and pressure sensor with local pressure and temperature detection display, and can, based on the detected medium temperature and pressure, convert the volume flow rate and total flow rate of the flowmeter under working conditions into that under standard conditions. Moreover, it has output interfaces for a variety of signals, to facilitate networking with other secondary instruments or computer systems to form a network management system. Its main technology reaches the domestic advanced level and is an ideal instrument for gas flowmeters in urban gas, petroleum, chemical, metallurgical and other industries.

Feature
Adopt the high-precision digital temperature and pressure sensor to automatically detect the temperature and pressure of media, correct the temperature, pressure and compressibility factor and convert the volume flow rate and total volume flow rate under working conditions into that under standard conditions.
The digital temperature and pressure sensor are independent accessories. The detection accuracy is unrelated to the corrector, so that separated calibration and verification are feasible. Data communication with the corrector is performed by the I2C interface. They are inspected and replaced weekly and can be easily maintained.
The digital pressure sensor comes with temperature correction function, high pressure detection accuracy, good long-term stability and low temperature drift.
