Ordering Guide

To place an order, please consider the following options and notes:

1. Digital displays are available for Ye junction boxes, supporting only 4mA to 20mA DC output.

2. Transmitters with M6 or M7 indicators require a power supply of ≥16V DC.

3. Specify the cable material if different from the default PE cable.

4. Ensure the measured media is compatible with the wetted material and specify the media density if it's not water.

5. In thunderstorm-prone areas, use a lightning protection device and ensure reliable earthing.

6. Contact the supplier for additional requirements or metrology verification certificates.
