Design And principle actions

flow meter consists of from primary flow converter (FC) and electronic converter unit (ECU).

PPR represents by yourself frame, in internal parts of which located two parallel, curved measuring tubes, electromagnetic coil ( coil excitement) And detectors, representing by yourself assembly from coils inductance And permanent magnet, thermistor.

The operating principle of a mass flow meter is based on the use of the Coriolis force that occurs during movement . measurable Wednesday V tube PPR, performing transverse fluctuations.
Under the action of the excitation coil, the PPR tubes perform oscillatory movements V opposite, relatively Friend friend, directions.

General view

relatively Friend friend, directions. Detectors installed on each side measuring tubes PPR, generate sinusoidal signals forms describing movement tubes relatively each other. Liquid, incoming V The primary flow transducer is divided into two equal parts and flows through each measuring tube. As the fluid moves through the measuring tube , a strength Coriolis. In input parts of the tube strength Coriolis directed against the flow tubes, on a day off parts of the tube power Coriolis directed By direction movements tubes. Like this in this way, at the entrance parts measuring tubes The Coriolis force prevents the tube from moving, but in the outlet part it promotes it, which leads to To twisting measuring tube. As a result of the tubes twisting, the detectors generate sinusoidal signals with shift phases fluctuations opposite sides of the measuring tubes of the PPR. Difference phases fluctuations opposite sides tubes directly proportional mass consumption.

The density of the measured medium is determined by way measurements period vibrations of tubes PPR, which directly proportional – linen density environment.

EBP provides nutrition PPR And processing electrical signals, incoming With PPR. EBP carries out registration of results measurements And indication measured data on built-in display, generates output signals: current 4-20 mA, frequency-pulse, digital HART, RS485 ( ModBus) RTU) for information transfer V RSU.

Flow meters are being released V two executions : integral And separate. Integral execution characterized by the installation of an electronic converter unit directly on primary converter consumption. Separate the execution is characterized by remote installation electronic block converter from primary converter consumption at help connecting cable.
