Metal Tube Float Flowmeter
Product Description
Metal tube Float meter (also called metal tube rota meter), also known as production and research using variable area measurement principle, has the characteristics of simple structure, reliable operation, wide application range, high accuracy and convenient installation. Compared with the glass rotor flow meter, this series of flow meters have the characteristics of high pressure resistance, high temperature, safety and reliability, and concise reading.
Suitable for measuring liquids and gases. All metal structure, there are indicating 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, with magnetic filters and special specifications.
Application
Widely used in petroleum, chemical, power generation, pharmaceutical, food, water treatment, etc. Complex, harsh environmental conditions, and flow measurement processes of various media conditions.
Principle
The float of the metal tube float flow meter moves the float upward 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.
