Liquid Level Gauge Operation Methods

Glass Plate/Tube Liquid Level Gauge
Slowly open the lower liquid phase valve and the upper gas phase valve to allow the medium to enter the measuring cylinder smoothly.

Magnetic Flap/Floating Ball Liquid Level Gauge
First, slowly open the lower liquid supply valve to allow the medium to enter the main tube smoothly, preventing the float from rising too quickly and causing the flaps to flip erratically or get stuck.

After commissioning, use the calibration magnet to check whether the flaps are flipping normally (red below the liquid level, white above).

Ultrasonic/Radar Liquid Level Gauge (Non-contact)
Install vertically at the top of the vessel, ensuring the probe is aligned with the liquid surface and avoiding interference from agitators, tank walls, etc.

Reserve a blind zone (usually 0.25–0.6 m; small blind zone models can be 4–6 cm) to ensure the maximum liquid level is below the lower limit of the blind zone.

After powering on, the device will automatically calibrate, or the range, units, and other parameters can be set using buttons.

Submersible Hydrostatic Liquid Level Gauge
Immerse the probe to the bottom of the container (or the specified depth), ensuring the vented cable is intact.

Connect the power; the hydrostatic sensor will automatically compensate for atmospheric pressure and output a 4–20 mA signal proportional to the liquid level.
