- Product Description
-
This instrument uses a high-performance microprocessor chip to collect flow, temperature, and pressure signals. The signals are amplified, non-linearly corrected, and processed for instantaneous and cumulative flow, as well as temperature and pressure display. Flow signals can be output in unit pulse, (4~20)mA, and RS485 formats. It can be paired with various flow meters for measuring the volumetric flow of various liquids, gases, and steam, as well as standard cubic volume flow and mass flow.
Main features of the instrument:
- 5 segment instrument coefficients, automatic non-linear correction;
- Arbitrary small flow signal cut-off can be set;
- Automatic compensation for medium temperature and pressure;
- Parameters and flow values set internally can be permanently saved during power outages.
- With a backlit LCD screen, it can simultaneously display the instantaneous and cumulative flow of the medium;
- Can select volumetric flow, standard cubic volume flow, and mass flow display;
- High accuracy, good repeatability, and high reliability;
