The SandQ sensor is installed a few pipe diameters downstream of a bend, where the flow is turbulent. The SandQ measures sand/particles through passive ultrasonic technology; it detects the ultrasonic signal that is generated by particles impacting on the inside of the pipe wall, just after the bend where the sensor is located.
The flowing media may be a single-phase liquid or a multiphase flow, and all signal processing is done internally by a DSP engine before the results are sent to a computer or control system (no Calculating Interface Unit required).
The SandQ is delivered fully calibrated and there is no need for individual site calibration to operate this unit, which can be simply clamped to the pipe wall.
With the ClampOn SandQ, field operators can evaluate sand data in real time and make the decisions required for optimized production.
