Metering and measurement with PLUM volume correctors

A PLUM volume corrector is a device used in gas metering systems, particularly in natural gas distribution, to convert the measured gas volume under operating conditions to base (standard or normal) conditions.

This is vital for accurate measurement because gas expands and contracts depending on temperature and pressure, so readings need to be corrected to base conditions for accurate billing and reporting.

It’s important to understand the key benefits of using a PLUM volume corrector:

Accurate measurement: Corrects gas volume for pressure, temperature, and compressibility factor (Z-factor), ensuring you obtain the true gas volume at standard or normal conditions.

Regulatory compliance: Ensures compliance with industry standards and legal metrology regulations, which often require corrected volume data for billing.

Real-time data logging: Logs and stores data such as flow rate, pressure and temperature, which can be used for diagnostics, auditing and reporting.

Remote monitoring and communication: Many PLUM models support remote access via communication protocols (such as Modbus and NB-IOT for example), allowing for easy integration into SCADA systems or smart metering platforms.

Improved billing accuracy: By converting volume to base conditions, it minimises billing disputes and ensures fair charges for both supplier and customer.

Compact and easy to integrate: PLUM devices are often compact, robust and designed for straightforward installation with existing gas meters.

Battery-powered: Suitable for remote locations with no power supply, with long battery life (typically multiple years).

If you're in the gas industry or managing utility infrastructure, using a PLUM volume corrector helps ensure operational efficiency, compliance, and accurate financial transactions.
