LG-300 floating ball continuous liquid level meter
MajorityTank and box liquid levelLiquid level measurement
LG-300 floating ball continuous liquid level gauge uses the floating ball to move up and down with the liquid, thereby triggering or releasing the magnetic reed switch in the tube, and the output is processed by the circuit.4-20mA or other different standard models.featuresMulti-interface measurement, easy to install, corrosion-resistant,covering most measurement requirements. Suitable forLiquid level measurement of various tanks and boxes, optionallocal display.
LG-300 floating ball continuous liquid level meterIt uses the magnet in the float ball to change the voltage dividing circuit composed of the resistance in the connecting rod and the reed switch as the liquid level changes. The smaller the gap of the reed switch, the higher the accuracy. The divided voltage signal can be converted into 0-4-20mA or other different standard models through the converter. The indicator can be used with other gauges for long-distance indication. It is a liquid level indicator with simple principle and good reliability!
