Overview

KVAF metal tube float flowmeter

Product Details

KVAF metal tube float flowmeter

Widely used in industries such as petrochemicals, steel, electricity, metallurgy, light industry, food, pharmaceuticals, water treatment, etc., for flow measurement and process control of liquid, gas, and steam media in the industry.

Suitable for flow measurement of small caliber and low velocity media.
Simple structure, reliable operation, low maintenance, and long service life.
The requirements for the straight pipe section are not high, and the measurement accuracy of the instrument can be ensured by the first 5D and the second 250mm.
The wider range ratio is 10:1.
The non-contact magnetic coupling transmission structure ensures stable displacement transmission.
LCD display, can alternately display instantaneous flow and cumulative flow, optional with backlight.
Low hardware quantity, low power consumption, strong anti-interference ability, high reliability, and good adaptability.
HART communication. The converter adopts a low-cost HART communication device based on a microcontroller.
Intrinsic safety and explosion-proof types are optional.
The linearization output device of the intelligent metal tube float flowmeter has been used to achieve linearization of data display.
