ance. The information in these instructions is checked regularly and any corrections are included in the next edition.
2. Product description
Cordonel is a static bulk water meter for industrial and commercial applications. The meter uses ultrasonic technology based on the transit time
method. The meter is equipped with three ultrasonic paths, which are arranged in pairs and alternately send and receive ultrasonic signals with
and against the direction of flow of the water. The time the signal takes to go from the transmitter to the receiver is measured. The flow velocity is
calculated using the differing transit time of the signal with and against the flow. The flow volume is calculated by multiplying the flow velocity by
the constant cross-section of the measuring tube.
3. Uses
- For measuring potable water up to 50 °C
