1.3.2 Product operation principle
The device is installed directly on the measuring branch pipe of
wellhead fittings and does not require measuring cables. The product
performs acoustic pulse generation in annular space, reception,
transformation and analysis of acoustic response (echo signal), fluid level
determination, pressure control at wellhead. The product operates under
the internal program under the control of the built-in microcontroller,
which processes information from primary sensors, performs level
calculation, records the values of controlled parameters (pressure and
level) in its long-term memory, and provides communication with external
devices (PC).
The level sensor is automatically supplied by the built-in lithium-ion
battery. For its charging the product has a built-in charger with software
control, allowing you to properly maintain the battery. The lithium-ion
battery does not need to be discharged before it can be recharged, so once
the battery is powered up, the product will start to charge immediately.
