The sensors are connected to a pipe with liquid passing through and turning a paddle wheel, the primary device calculates the speed as the paddle is turned. Paddlewheel Flow Sensors or Turbine: One of the most common types of flow sensor. The transmitter produces an output signal from the raw transducer signal. The transducer senses the fluid that passes through the primary device.
Flow sensors are available as time measuring units (these measure flow rates over a set time period) or they can be totalising flow meters that continually measure the medium passed through.įlow sensors consist of a primary medium connection device, transducer and transmitter. They can also be known as flow gauges or liquid meters. Flow sensors or flow indicators are flow meter devices used to measure the amount of liquid, gas or vapour that passes through them.
