With all Fiscal type metering systems the methodology is to minimize inaccuracy throughout the system. Our Bi- Directional Provers provide the most reliable means available to verify flow meter readings and establish meter factors. It is an easy and accurate way to calibrate flow meters in the field, in order to ensure exact measurement of liquid flow.
PIE Group can provide specialist equipment for calibrating the provers too. Prover calibrations are made in the field using volume tanks or master meters. Both systems can be provided to industry standards, and fixed or mobile systems can be supplied separately or integrated with the provers.
