How to choose a water flow meter

Date: 10/09/19 | In: Water Meters


Selecting a water flow meter is crucial for accurately measuring the flow rate of water, sewage, or trade effluent. With hundreds of options available, choosing the right one requires understanding your specific needs and objectives.

Understanding Water Flow Meters

A water flow meter is designed to measure either the volumetric or mass flow rate of liquids. It plays a vital role in various industries and organisations, influencing decisions related to efficiency, compliance, and operational costs.

Factors to Consider

Several factors should influence your choice of flow meter:

  • Legal Obligations: Compliance with discharge licenses and regulatory requirements.
  • Site Conditions: The location’s characteristics and environmental factors.
  • Fluid Characteristics: Type of liquid, presence of contaminants, and temperature.
  • Flow Conditions: Normal and peak flow rates, operating pressure, and pipe diameter.
  • Sensor and Data System: Choosing the most suitable technology and data collection method.
  • Other Variables: Specific requirements unique to your application.

Detectronic Expertise

At Detectronic, we specialize in providing tailored monitoring solutions for water and sewage companies (WaSCs), industrial firms, and more. Our extensive experience ensures we can help you find a water flow meter that meets your long-term needs and delivers a solid return on investment.

Technology Options

Manufacturers offer a range of technologies to meet diverse application needs:

  • Ultrasonic Flow Meters: Utilize sound waves to measure fluid velocity non-intrusively, ideal for wastewater and corrosive liquid applications with low maintenance costs and high reliability.
  • Electromagnetic Flow Meters: Measure flow based on the conductive properties of the fluid interacting with a magnetic field.
  • Coriolis Flow Meters: Measure flow based on the twisting or vibration caused by fluid movement through a U-shaped tube.
  • Cone Flow Meters: Calculate flow rates by measuring differential pressure around a cone placed in the pipe.
  • Orifice Plate Flow Meters: Determine flow by measuring pressure differences before and after a constricted area in the pipe.
  • Propeller/Turbine Flow Meters: Measure flow by detecting the rotation of a propeller or turbine in the pipe.
  • Venturi Flow Meters: Use differential pressure to measure flow rates by comparing pressure changes in a constricted pipe section.
  • Vortex Flow Meters: Measure flow by detecting vortices created by an obstruction in the pipe.
