Measuring in open channel

For an easiest installation and use with an open channel (venturi or “V” notch), it is better to ask for a free factory calibration when the SAP 100 display unit is not is not ordered at the same time.
After fiting the EchoTREK on its stand, it is possible to adjust the 4/20 mA output using the magnet key.
