Irga-PU standard calibration rig

Irga-PU standard calibration rig is designed for testing and calibration of vortex, jet, turbine, rotational, ultrasonic and other flow meters (meters, flow meters) to measure the flow rate and volume of gaseous media (natural gas, air, steam, etc.), as well as for calibration of household gas meters.

More description

Advantages

Wide range of rate reproduction: allows to calibrate flow meters and counters, both domestic and industrial, with DN 500
High automation: allows setting and adjusting the flow programmatically from the stand operator’s computer - calibration is accelerated, i.e. time and energy are saved
The types of measuring instruments for which the calibration rig is intended, the ranges of flow rates, the types of reference flow meters are determined by the customer's terms of reference.
The remaining parameters of the rig and its adjustment to a specific room are designed by the experts of Globus LLC based on the customer's terms of reference.
