Metal Tube Variable Area Flowmeter for Water

Suitable for measuring liquids and gases. All metal structures, there are indication type, electric remote transmission type, corrosion resistant type,

high voltage type, jacket type, explosion-proof type. 

With 0-10mA, 4-20mA standard analog signal output and field indication. Accumulation, digital communication, on-site modification of measurement parameters, different power supply functions, magnetic filters and special specifications.

The float of the metal tube float Flow Meter moves the float upwards with the change of the flow rate in the measuring tube, and the buoyancy of the float and the gravity of the float reach a balance at a certain position. At this time, the flow annulus area between the float and the Orifice Plate (or cone tube) remains constant. The area of the annular gap is proportional to the rising height of the float.That is, the rising position of the float in the measuring tube represents the flow rate, and the position of the changing float is transmitted by the internal magnet to the external indicator, so that the indicator can correctly indicate the flow value at this time. This makes the indicator housing not in direct contact with the measuring tube, so even if limit switches or transmitters are installed, the instrument can be used under high temperature and high pressure working conditions.

Widely used in petroleum, chemical, power generation, pharmaceutical, food, water treatment, etc. Complex, harsh environmental conditions, and flow
