Electric remote transmission metal tube float flowmeter
Product details
Product Introduction
Electric remote transmission metal tube float flowmeterAdopting the principle of variable area measurement, suitable for measuring liquids and gases. All metal structure, including indicator type, electric remote transmission type, corrosion-resistant type, high-voltage type, jacket type, and explosion-proof type. It has standard analog signal output and on-site indication of 0-10mA and 4-20mA. Accumulation, digital communication, on-site modification of measurement parameters, different power supply functions, with magnetic filters and special specifications. Widely used in industries such as petroleum, chemical, power generation, pharmaceuticals, food, water treatment, etc. During the flow measurement process under complex, harsh environmental conditions, and various media conditions.
1、 Principle of electric remote transmission metal tube float flowmeter
The float in the measuring tube moves upwards with the change of flow rate, and at a certain position, the buoyancy acting on the float reaches equilibrium with the gravity of the float. At this time, the circulation gap area between the float and the orifice plate (or cone tube) remains constant. The annular gap area is directly proportional to the rising height of the float, that is, the position where the float rises in the measuring tube represents the size of the flow rate. The change in the position of the float is transmitted by the internal magnet to the external indicator, so that the indicator correctly indicates the current flow rate value. This means that the indicator housing does not come into 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.
