Custody Metering System

Custody Metering System at the delivery point where oil or gas is changing hands forms the basis for invoicing. Every cubic meter of product has to be accurately accounted for its delivery conditions, such as pressure, temperature, contaminants and energy value, closely monitored and recorded.


Custody Metering System in oil & gas industry have rapidly evolved in terms of sophistication, accuracy and reliability : countless factors have to be taken into account in the design of the metering system, requiring multi-disciplinary specialists with very specific experience and knowledge

Configuration of the metering system

Configuration of Custody Metering System

Valmax’s process analyzer system consists of the following equipment:

Flow Meter

Depending on the type of fluid you want to measure, it can consist of flow meters in various ways, such as Ultrasonic, Turbine, Coriolis, orifice, and the measured flow rate is sent to the Flow Computer.


Send measured data to Flow Computer via Temperature & Pressure Transmitter in Measurement Fluid

Gas Chromatograph

The energy value of the flow rate is derived by measuring the calorific value of the reference volume of the fluid, such as natural gas.

Flow Computer

Receive data from Flow Meter / Transmitter / Gas Chromatograph, calculate mass, volume, and calories, store/process/implement/transmit data in real time, and transmit data by communication at the same time.
