How Does it Work?

• 1. Setup : In the semi-automatic method of operation, users can pre-enter the desired flow rates and size of meters being tested and they just need to press start. The system will automatically set the desired flow rate and after measurement, will move to the next flow rate. Once all the flow rates for a particular size are completed, the meters can be removed easily using our pneumatic clamping and you can move over to the next batch.
• 2. Controlled Flow: Using the reference meter and VFD to control the pumps, we can control the rate of flow of water through the pipes by checking the value on the reference flow meter.
• 3. Comparison: The meter’s reading is checked against the actual amount of liquid that passed through the master device. For comparison method, the master is the reference flow meter. For Gravimetric method, the master is the weighing scales.
• 4. Adjustment: If the meter isn’t accurate, it’s adjusted to ensure it measures correctly and the process is repeated. The adjustment of the meter is through setting a factor called the “k-factor” and this value should not be changed between calibrations as it affects the value and accuracy.
