Flow Surveys

Providing flow surveys for a multitude of applications and industry sectors.

One of Detectronic’s core competencies is to conduct flow surveys. For water companies, civils contractors, MOD sites, construction companies and other companies undertaking building developments, we carry out surveys in wastewater sewer channels. Typically carried out for an 8 week period, surveys are used to measure depth and velocity of the water within the network.

Flow surveys are also an essential for many industries to maintain safe operations and help you understand the process better. Clamp on flow meters can measure almost any liquid in almost any process line without the need for cutting, welding or disruption to the process.

Water Utilities

Detectronic uses ultrasonic flow measurement technology to help water companies manage their networks and processes effectively. Flow surveys may be used for:

  • Early detection of flooding
  • Understanding inflow and infiltration rates
  • CSO monitoring
  • Smart network monitoring of the sewer
  • Understanding sewer capacity and areas susceptible to flooding
  • Flood risk assessments

Flow surveys are often extended for longer terms and into permanent monitoring solutions to help manage the wastewater network more efficiently and to understand the environmental conditions when trying to understand the causes of flooding or bottlenecks.

Detectronic uses water flow meters to accurately measure depth and velocity in sewer networks. Level monitors are used measure water levels and rain gauges are used to monitor rainfall rates.


Regardless of what sector you operate in, be it food and beverage, pharmaceuticals, or paper, flow surveys provide essential information at every stage of the manufacturing process. Flow surveys tell you flow velocity and help you detect weaknesses, leaks and blockages. With that information you can make provisions for improvements, find efficiencies and save costs.

  • Trade effluent monitoring
  • Understanding the volumetric flow through a process line
  • Validation of an installed metering system
  • Evaluate whether an un-metered line is suitable
  • Check if pumping equipment is working as expected
  • Flow verifications

Before a process is modified or works have been expanded, it it important to understand what is happening and how it all works. We would take accurate measurements at all the relevant process variables to help engineers understand the hydraulic performance of the system.

Detectronic has a range of flow meters to fit your requirements including radar flow meters and area velocity flow meters for open channels and partially filled pipes.

Remote Data Management

All Detectronic remote data management portals use a user friendly interface allowing you to manipulate it into an easy to digest, interactive format. Web based, your information is accessible wherever and whenever you need it. With the ability to set up email or SMS alerts, you don’t even need to log in to know when your network needs attention.

For a flow survey, flow rates, velocity and depth information is recorded at regular intervals, typically at a 2-minute logging rate throughout the survey. Data is transmitted to one of Detectronic’s data platforms

Intelligent remote monitoring and alarm handling helps to ensure your network is running at optimal levels, assets are protected and you are minimising operating costs and risk.
