High Accuracy Variable Area Wet Type Liquid Gas Metal Tube Rotameter Flow Meter
High Accuracy Variable Area Wet Type Liquid Gas Metal Tube Rotameter Flow Meter Description:
Metal tube rotameter is a variable area flow meter based on float position measurement. Adopting all-metal structure and Modular conceptual design, it is widely used in flow measurement and process control under complex and harsh environment in various industries, with small volume, small pressure loss, large range ratio (10:1), etc. stream,especially suitable for mediums with low current velocity and low flow rate.Due to its excellent performance,reliability and competitive price, it is widely used in the fields of oil, chemical industry, steel manufacture, light industrial,water etc. Metal pipe flowmeter takes many different materials and is suitable for flowmeter measurement of all non-corrosive, corrosive and strong corrosive mediums.
High Accuracy Variable Area Wet Type Liquid Gas Metal Tube Rotameter Flow Meter Feature:
1.Single axle, smart display, high reliability, easy maintenance, long life time.
2.Less requirement on the tube.
3.Flow ratio:10:1, special type: 20:1.
4.Suitable for measurements of mediums with small pipe and low flow rate.
5.LCD display, displaying instantaneous flow and whole flow at same time.
6.Non-contacting magnetic coupling transmission.
7.Metal structure, suitable for strong corrosive mediums and environments with high temperature, high pressure and flammable and explosive conditions.
8.Two-wire available, battery and AC supply to choose.
9.Multiple parameters calibration function, data restoration and back-up, power-fail protection function.
