Where the meter has been approved by the sanitary requirements of the European Hygienic
Engineering and Design Group, you MUST give consideration to:
• Installation - install the meter at an angle to allow self-draining (see illustration).
• Cleaning fluids - cleaning fluids should flow uphill with a velocity rate greater than
1.5 m/s / 5ft/s. If the process flow is downhill, install a flow restrictor downstream of the
meter. This will make sure that the meter is completely filled with the cleaning fluid.
• Process connections and seals MUST be in accordance with EHEDG documentation.
The manufacturer also recommends that you refer to EHEDG (www.ehedg.org) document
number 8 "HYGIENIC EQUIPMENT DESIGN CRITERIA".
