FLOW MONITORING

Using a portfolio of data logging equipment we can provide portable or permanent flow measurement devices that enable accurate flows to be measured at a range of measurement intervals ranging from seconds to hours.

Loggers can be installed for periods from 24 hours to 14 days in order to assess daily fluctuations or using GPRS for permanent installations that connect to a specialist system and alarm monitoring software. Typical applications:

Uses of flow monitoring

  • Industrial process flows
  • Billing and accounts management
  • Water use audits, efficiency surveys and submetering
  • Zone and DMA network monitoring
  • Hydraulic computer model calibration
  • Fire mains testing
  • Leakage measurement

Data Logger Maintenance

We can provide a data repository of all flow meters, data loggers, confined spaces and maintenance visits using GPS enabled field capture devices and our specialist software ‘loggers online’. Routine servicing or replace on fail maintenance contracts can be established. At any one time, we maintain over 20,000 data loggers around the UK.

Sewer Flow Surveys

SSI via OnSite is a world leader in the field of sewer flow surveys, having been involved in the inception of flow survey technology back in the 1980s.

Dual-sensor Flow Monitors

The dual sensor flow monitors offer high levels of accuracy and reliability, combined with an integrated telemetry solution to enable real time data collection.

Acoustic Doppler flow meter

for precise measurement of flows in large and medium diameter pipes, in variable hydraulic conditions. Slow velocities measured accurately.

Long and short term flow surveys: accurate depth and velocity measurements in pipelines and wwatercourses combined with rain gauge measurements, to provide modelling engineers with critical data about the performance of their pipeline networks.
