MA-920 Series Intelligent, Pure Electronics Micro Flowmeter

General

MA-920

MA-920is a metal tube variable area flowmeter for small flow measurement which has local indication with transmitting of minute flow rate of liquids and gasses.
The existing micro flowmeters generally need asignal linearizer due to mechanical problem of very minute sensing part.
In MA-920, integrated microprocessor takes care of these automatic compensation based on indevisual stored callibration data and achieves high accuracy even for small flow rate.

Features

·  Very minute flow (upto 3L/h(Water)) measurement is possible
·  Easy-to-read digital LCD display
·  Compact design
· Safety for high press. and high temp
· 2-wire DC4 to 20mA output
·  Analog output with Exd IIC T6 flame-proof construction is provided
