Installation Do not open or alter any part of the product, which would lead to malfunction and irrecoverable damage. Depending on the applications, the products can be used for open space environmental data collection or as an insertion meter for inline gas flow measurement.
  • Page 10 PFLOW1000V_1620-21914-0006-E-0224 Figure 4-1. Preparation for the insertion fixture. Make sure there is no debris or excessive particles left in the pipe during the preparation of the product fixtures on the pipe. Refer to the graphs below, per OIML R137 recommendations, the upstream of the meter should have a 20xDN straight pipe length, and downstream should have a 5xDN straight pipe length.
  • Page 11 PFLOW1000V_1620-21914-0006-E-0224 Please note: a. The product is not designed for hazardous zone applications, and not for corrosive gases; b. The installation should also be at locations where it is away from valves, sharp turns, and other cases as described in OIML R137 as those would generate flow instability and causing unstable outputs.
