Meter Runs

High Pressure Single Chamber Orifice Fitting


EPS meter runs form an integral part of the measuring system, and are used both up and downstream of the EPS meter. EPS meter runs are manufactured to meet stringent industry measurement and piping standards and safety' guidelines. Designed to meet the end users expectations, they are designed to ensure that the meter run can be installed with total confidence.

Tapping points for instrumentation can be provided within the design for both upstream and downstream connections points, e.g. thermo-wells, densitometers. All of the EPS DP meters can be included into a meter run as well as flow conditioners/straighteners, DP transmitters, single point data transmitters, Diagnostics for CBM (Condition Based Monitoring) and flow compUters can be included within the solution to make a more complete ’Measurement System’.

EPS meter runs are designed to suit and comply with the specific customer requirements and needs. As with the DP meters EPS can offer, our meter runs can be supplied in all materials from carbon steels through to Super Duplex. Pipe end configurations are available as either welded or flanged in accordance with a variety of industry recognised flange standards or in compliance with the client specific flange requirements.

EPS Meter runs are manufactured in strict accordance with industry standards and are supplied with detailed measurement verification, materials certification and where applicable in compliance with PED 97/23/EC (Pressure Equipment Directive) and other client/region specific codes.

It is the combined manufacturing and dimensional accuracy of the meter and that of the meter run piping that provides the ’system accuracy’.

It is for that reason why EPS recommend purchasing a complete measurement system from EPS, comprising of an EPS DP meter and meter run, to optimise the metering accuracy.

All EPS meters can be supplied complete with a meter run, to further optimise the metering accuracy.
