Excels Fabrication and Engineering range of metering skid are a part of the plant, pre-assembled on steel support, dedicated to the measurement of gas or liquid products. In particular, the main variable to be measured is the flowrate. Depending on the selected technology and on the Client Specifications, the measured flow rate can be a mass flowrate or a volumetric flow rate. The metering skid often performs additional treatments, such as pressure-reduction by means of valves, filtration (depending on fluid cleanliness requirements for measurement), and flow control by means of flow control valves. Fiscal metering skids often include a calibration system (Prover) as well.
