Measuring Liquid

Flow measurement applications, used to measure the quantity or rate of a gas, steam, or liquid flowing through a pipe, provide consumers with a range of veritable benefits. Flow meters offer accuracy, stability, and consistency that are essential to the success of an application’s processes; measuring these materials can enhance an application and drastically reduce the room for error.

When implementing a liquid industrial flow meter, you first must thoroughly assess the needs of your application, as different components call for different tools. Temperature range, rate of flow, pipe size, and cost are all important factors to consider before deciding on what type of flow meter best suits your working environment.

Liquid flow measurement varies by industry, but typically include units such as gallons per minute, liters per second, bushels per minute, or cumecs (cubic meters per second).  Some of the most common liquid measurement devices include:

  • thumb-proline-promag-10d.pngElectromagnetic — Often used to measure arduous and corrosive liquids, these devices can track flow in varying directions with consistent accuracy. In these meters, the liquid acts as a conductor while the coils energized outside of the flow tube form a magnetic field. However, electromagnetic flowmeters can only be used for electrical conductive fluids and consume a rather high amount of power.
  • coriolis.pngCoriolis — Another tool with the ability to measure both liquids and gases, these devices provide direct mass measurement resilient to changes in temperature, pressure, density, or viscosity. To measure the amount of mass passing through an element, this flowmeter employs the Coriolis effect, in which the deflection of moving objects in motion is relative to a reference frame in rotation.

At Endress+Hauser, we provide customers with a range of measuring principles including mass flow based on thermal principle or the Coriolis, volume flow based on ultrasonic principle or vortex, and electromagnetic measuring of volume flow.

We are proud suppliers of a range of highly functional liquid measurement systems.
