Vortex Flow Meter (HMT. VFM)

Product Specifications

Product Description

Summary

With on-site display function, Can be built-in or integrate temperature, pressure sensor to realize compensation function, With "HART" protocol advanced features. Intelligent circuit according to the characteristics of vortex sensor, the detection and closely integrated totalizer. We use sophisticated low-power 128 × 64 full DOT matrix LCD display, local display instantaneous flow and total flow, and measuring the temperature and pressure compensation, display data-rich and intuitive. Common operating principle set the menu, and prompts the use of English letter, clear and intuitive, easy to operate

Features

1) Multi-point linear correction to achieve the full real-time linear compensation, to achieve a linear ability to compensate

2) To convert working conditions flow rate into the mass flow or volume flow under standard conditions directly, measuring simple and precise

3) 12 kinds of compensation algorithm to fit almost all working condition compensation calculation, rely on external data signal correction curve

And the calibration of standards-based way, greatly improve the measurement accuracy.

4) Through manual setting to do various amendments, parameters setting, functions setting thus that the instruments adapts to various pipeline and

All kinds of measure media.

5) Signal Output: Three wire with a linear correction of the pulse output and three-linear correction current output, with RS485 communications,

And battery-powered; The wire 4-20mA output can be multi-linear correction, and provides isolation of the original pulse output.

6) HART communication can be configured and read the measurement data comply international standards
