Pipe piston testing unit "Sapphire-M NGI" installed on KAMAZ 4308 chassis.

Purpose:
TPUs are intended for:
- TPU of the 1st category (as a working standard of the 1st category): for measuring the volume of liquid during calibration and verification of flow converters with electric pulse output signal (liquid meters) and other TPUs;
- TPU of the 2nd category (as a working standard of the 2nd category): for liquid volume measurement during calibration and verification of flow converters with electric pulse output signal (liquid meters).
The area of TPU application is metrological centres and liquid metering points.
