Draft and Ballast Tank level measuring system Model: BAL-2000 / Pneumatic type
Model: BAL-2000/ Pneumatic type
General introduction
The pneumatic level measurement system and ballast are designed to measure the level of ballast tanks, tangle levels, and fuel oil tanks of ships. The system uses sensors that measure gas thrust levels and is used to measure levels of different types of tanks.

Structure and principle of operation of the system
The BAL-2000 includes an Air purge gas pusher, a dual brake valve, a payroll adjustment device, a direction adjustment valve, a gauge, and a similar display for each tank.
The principle of operation is based on measuring the hydrostatic pressure of the liquid by providing low constant air flow into the measuring tube, called the Sounding tube, at the outside below. When the air escapes through the mouth of the clean filter pipe at the bottom of the tank, the gas pressure corresponds to the level of liquid accumulated in the Sounding tube. If the specific weight (weight) of the known liquid and the pressure in the Sounding tube are measured, the distance from the pipe door to the surface can be calculated using the above expression. The pressure is read on the scale divided by the metric in meters or the volume or percent of the head of the tank.
