The MSR175 shock transportation data logger is the newest miniature logger from MSR.  The MSR175 more >

A flow meter is an instruments designed for the measurement of the flow rate and volumes of liquids and gases and this section includes flow meters suitable for monitoring the flows of various different liquids and gases. The flows of liquids and gases can be measured in various different ways and these can be more or less suitable for specific types of flow and the flow profile of your media.

1. Oval gear meters are ideal for batching and controlling volumes
2. Electromagnetic flow meters can be ideal for monitoring sewage discharges from waste pipes.
3. Portable ultrasonic meters are non-invasive and can be perfect for spot checking flows
4. Fixed ultrasonic meters are the best solution where it might not be possible to break into the pipeline.
5. Multi-jet flow meters can be ideal for monitoring domestic flow metering Including WRAS approval for drinking water
6. CDI meters are designed specifically for compressed air flow monitoring

If you are having trouble selecting the right meter for your application, please contact us to discuss your requirements.

Electromagnetic Flow Meters (Magnetic Flow Meters)

An Electromagnetic flow meter (Magmeter or Magnetic flow meter) is a volumetric flow meter that uses Faraday's Law to measure the flow of conductive fluids passing the sensors. This means these meters are ideal for the flow measurement of any conductive, or water based, liquids and the absence of any moving parts makes these type of meters ideal in wastewater applications and were low pressure drop and low maintenance are required. These meters do not work with non-conductive fluids, eg distilled water, hydrocarbons or many non-aqueous solutions.

Vortex Flow Meter
A Vortex flow meter is designed for flow measurement where any moving parts in the flow could create problems and due to having no moving parts, they are very low wear compared to other types of flow meter. The working principle is to create an oscillating vortexes in the fluid, gas or steam as the flow passes a bluff body. A sensor mounted to the shedder bar can determine the flow based on the amount of force being applied to the shedder bar.
