Automated proving rig APU-G-011/5000 is intended for calibration and proving flow meters working on air, natural gas,
and other gases and mixtures.
Automated verification rig APU-G-105/12 is intended for diagnostics, calibration and verification of household gas meters having pulse output signal, rotometers, aspirators, rotometric tubes, diaphragm meters.
APU-G-011/2500 installation is intended for calibration, verification and service of flowmeters operating on air, natural gas, other gases and their mixtures.
Energofow AG has a core team for design, fabrication and installation of Calibration &
Verification systems for all types of flow meters.
1. Calibration and Proving Rigs for gas meters (working medium “air” at atmospheric
pressure):
– with critical nozzles;
– with reference (master) meters;
– based on gravimetric method
– combined versions.
2. High pressure Calibration and Proving Rigs for gas meters (working medium “air“,
“natural gas”).
3. Automatic modular calibration rigs.
4. Automatic Proving Rigs for liquid flow meters.
5. Liquid and gas reference meters.
6. Portable flow rate standards for liquids and gases
Meters being proven are installed on the rig after the master meters.
This eliminates the possibility of contamination of reference meters from meter being verified. There is no need to clean the meters taken off the working unit. You can see the real defects of the meter before carrying out proving work.
Low-leg temperature sensors with a reaction time in the air stream of not more than 10 seconds are used
We are a Swiss company devoted to design, engineering and manufacture of flow-metering solutions and related products based on the modern ultrasonic technology
