Accurate water flow measurement is a key requirement in many industries. In the water industry, the increasing value of potable water around the world requires more accurate measurements and leakage detection. Use of water in manufacturing and production is coming under increasing efficiency pressures with an associated requirement for accurate measurement.

Within the oil & gas industry, many mature oil fields are producing large amounts of water along with the target oil, most of which is discharged back to the sea following treatment to reduce the oil content. Legislation is currently being introduced to reduce these discharges, however these can only be effective if the volumes can be measured reliably.

Water Flow Measurement Standard

TÜV SÜD National Engineering Laboratory operates the UK National Standard Test Facility for water flow measurement. The water facility is accredited to ISO/IEC 17025:2017. TÜV SÜD National Engineering Laboratory is a UKAS accredited calibration laboratory (No. 0009).

The water flow measurement facility is a modern purpose built flow meter calibration and evaluation facility. The facility has four separate flow lines, covering a wide range of flowrates in different line sizes. The test sections can be constructed to offer long straight lengths upstream or, if necessary, specific configurations designed to replicate actual installations.
