QPS Pneumatic Liquid Level Remote Sensing DeviceDetailed product description：

The QPS-100 pneumatic liquid level telemetry device is suitable for measuring and controlling the liquid level of ballast tanks, draft gauges, lubricating oil tanks, fuel tanks, and other tanks in various types of ships, shipyards, and oil platforms.

The QPS pneumatic liquid level telemetry device system provides a certain pressure and flow rate of air from the air source through a pressure regulator to the liquid level sounding tube inserted into the bottom of the measured cabin. After the air pressure is balanced with the static pressure of the liquid medium in the cabin, the excess air pressure overflows from the bottom of the liquid level sounding tube in the form of bubbles. The balanced air pressure inside the cabin is the depth static pressure of the liquid level, which can be directly displayed by a pointer display or converted into a 4-20mA liquid level signal through a P/I converter for remote transmission, and is transmitted from the height of the liquid level in the control room.

The QPS pneumatic liquid level telemetry device can continuously display the instantaneous values of liquid levels in each compartment
