Flow Sensors

Flow sensors or flow indicators are flow meter devices used to measure the amount of liquid, gas or vapour that passes through them. They can also be known as flow gauges or liquid meters. 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.

Flow sensors consist of a primary medium connection device, transducer and transmitter. The transducer senses the fluid that passes through the primary device. The transmitter produces an output signal from the raw transducer signal.

Types of Flow Sensor

Paddlewheel Flow Sensors or Turbine: One of the most common types of flow sensor. 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. This simple structure is compact and can perform a large-capacity measurement. Disadvantages are clogging and maintenance is required to cope with the axial wear otherwise the paddle needs replacing.

Variable Area Flow Sensors also known as Rotaflow meters: identified by their tapered tube and float designs. Widely used for gases and liquids flow measurement because of its low cost, simplicity, low-pressure drop and linear output.

Magnetic-Inductive Sensors: This type of sensor detects three process categories, volumetric flow quantity, consumed quantity and medium temperature.

Applications for Flow Sensors

Each type of flow sensor has its own specific applications and installation constraints. There is no one size fits all flow meter. The way to select the right flow meter is to think about the application as a guide, not the technology. Many of the technologies work well on many applications. Starting with the application will help to select the technology based on accuracy, cost, durability and reliability, rather than trying to make the technology fit the application you have. Can include the following applications:

  • Water treatment
  • Cooling systems
  • Industrial Washing Systems
  • Irrigation

Things to consider:

  • What is the fluid being measured, if not water what is its viscosity?
  • Rate measurement or summation?
  • Display or signal output?
  • What is the minimum and maximum flow rate, process pressure and process temperature?
