The WP series is approved for installation in horizontal and vertical positions, adhering to national regulations.
Observe flow sensitivity class U0/D0 and use a honeycomb rectifier for optimal results, especially with short inlet sections.
Ensure a straight outlet section and avoid reducing pipe diameter directly before or after the meter.
Align meter flow direction with pipeline flow and mount valves behind the meter where possible.
Install meter at the highest point to prevent air bubbles and protect against dirt with a filter.
Avoid pressure surges by filling the pipeline slowly and ensure the medium temperature does not exceed 50°C.
Install meter free of stress to prevent body damage and ensure pipeline pressure does not exceed the meter's working pressure.
Secure the connection interface with a safety device to prevent unauthorized disassembly of the meter.
Replacement by trained staff requires careful rinsing, pressure shut-off, and pipe emptying before proceeding.
Verify interface markings, remove old seals, clean surfaces, and use only genuine, undamaged seals for installation.
Ensure inlet area is free of deposits before installing a new unit and use suitable lubricants for seals.
Tighten the measuring insert crosswise and connect it with a sealing wire to prevent disassembly.
Declares product compliance with EC Measuring Instrument Directive 2014/32/EU and Wireless Communications Directive 1999/5/CE.
Details nominal diameter, permanent flow (Q3), attainable measuring range (Q3/Q1), overload flow (Q4), and minimum flow (Q1).
Provides data on transitional flow (Q2), pressure loss at Q3, start-up flow rate, and display range.
Specifies maximum temperature, operating pressure, and pulse values for Reed and modulator disc.
Lists dimensions including nominal diameter, overall length, height, installation height, flange diameter, bolt circle, and weight.
