All DSTRP water meters are individually calibrated. Hydraulic tests are carried out at 5 flowrates (Q1, Q2, Q3) on test rigs complying with standards ISO 4064/3 and ISO 4185, and are approved by a European notified body. A security tamper evident seal is fitted.
The DSTRP water meters are suitable for installation in horizontal pipelines and should be fitted such that the arrow marked on the body corresponds with the direction of water flow. The upstream pipework should rise so that the outlet is higher than the meter inlet ensuring that the meter is kept full of water. The water meters should be easily accessible to enable a clear reading from the counter.
DSTRP water meters are MID approved to metrological class MID R (Q3/Q1) 200H-50V. Meeting the requirements of Directive 2004/22/EC and European standard EN 14154.
