Philemon - Metal Tube Rotameters
Rota meter adopts variable area measuring theory, which is applicable for measuring liquid and gases and steam, it is all-metal construction, , it has local indication, remotely transfer, anti-corrosion type, high-pressure type, explosion-proof, etc.
Introduction
Variable area flowmeters is made up of flow sensor and flow indicator. Float is placed vertically inside of conical measuring tube and can freely move up and down along the conical tube owing to hydrodynamic effects.A high-performance permanent magnet is set inside float, by this way the magnetic field around permanent magnet will change along with the float moving up and down.When fluid keeps a stable flow value and float locates in a dynamic balance state in position, the magnetic field around permanent magnet keeps constant also.The magnetic signal will be transmitted in non-contact form by means of the flow Indicator mechanically connected to conical tube. In another word,the indicator is able to detect and process flow value of liquid by magnetic drive system and finally the corresponding flow rate value can be read from the scale on site. Also it can indicate outputs as standard electrical signal (4-20)mA / hart communication protocol.
It has 0-10mA, 4-20mA standard analog signal output and local indiction, accumulation, digital communication, field modification and measure parameters, different power supply function, it is widely applicable in petrol, chemical, power supply, pharmacy, food, water treatment industry etc.
