Estimates are that over 50 percent of all liquid flow measurement applications use this type of unit. The basic operating principle of differential pressure flowmeters is based on the premise that the pressure drop across the meter is proportional to the square of the flow rate.

Ready Mix Concrete-Batching, Mixing, Transporting, and Handling. Quality control of ready mix concrete is important as it has to be mixed and transported to different locations. Batching, mixing, transportation and handling of ready mixed concrete is discussed.
Jet pumps are a type of home water well pump that is used for lower flow rates than vertical turbine types. It is a horizontal end suction pump, put makes use of an ejector to assist the flow. Horizontal end suction pump with ejector either mounted on the pump (for shallow well services), or located down in the well. Domestic water wells: Water

They will not work well where the flow starts and stops repeatedly because there is a lag between the time the flow starts and the correct velocity is read by the meter. This means that (again with the exception of some units that are specifically designed to be very fast) magnetic flowmeters don’t work well in short-duration batching operations.

Now plant operators have new choices in instrumentation to simplify and improve the accuracy of sludge blanket level measurement. The simplest detectors use a sensor lowered on a cable by the operator. Sludge detectors can use ultrasonic sensors, where change in sound transmission from a transmitter crystal to a receiver is measured.
