Pure water flowmeter

1、 Working principle:

CS-LWGY-1802Pure water flowmeterWhen the measured fluid flows through the sensor, under the action of the fluid, the impeller rotates under force, and its speed is proportional to the average flow velocity of the pipeline. The rotation period of the impeller changes the magnetic resistance value of the magneto electric converter. The magnetic flux in the detection coil undergoes periodic changes, generating a periodic induced potential, that is, an electrical pulse signal. After amplification by an amplifier, it is sent to the display instrument for display.

A new intelligent instrument integrating turbine flow sensor and display integration, developed using advanced ultra-low power single-chip microcomputer technology,Adopting dual row LCD on-site display, it has obvious advantages such as compact structure, intuitive and clear reading, high reliability, no external power interference, lightning resistance, and low costThe instrument has three-point correction for instrument coefficients, intelligent compensation for instrument coefficient nonlinearity, and can be adjusted on-site. The high-definition LCD display simultaneously displays instantaneous flow rate (4 significant digits) and cumulative flow rate (8 significant digits, with reset function). Keep all valid data intact for 10 years after power failure. This type of turbine flowmeter is an explosion-proof product with an explosion-proof rating of ExdIIBT6.
