Tvpical Flowmeter Installation Blocking and Bypass valves should be installed if it is necessary to do preventive maintenance on the flowmeter without shutting down the flow system The Bypass valve can be opened before the Blocking valves are closed allowing the flow to continue while removing the turbine flowmeter for service IMPORTANT All flow lines should be purged prior to installing the meter To prevent possible damage to the meter install the meter ONLY in flow lines that are clean and free of debris Upon initial start up of the system a spool piece should be installed in place of the flowmeter so that purging of the system can be performed to remove all particle debris which could cause damage to the meter internals In applications where meter flushing is required after meter service care should be taken as to not over spin the meter as severe meter damage may occur To maintain an accurate flow measurement it is necessary to maintain a downstream pressure sufficient to prevent flashing cavitation Flashing of the liquid will result in an indication of flow significantly higher than the actual flow In order to eliminate this condition HP 257 Installation 11 adequate downstream pressure must be maintained The minimum required downstream pressure mav be calculated using the following equation Minimum Pressure 2xPr essureDrop 1 25xVapor Pressure Downstream pressure may be maintained by

19. s Size type of material and pressure rating should be the same as the flowmeter supplied The correct gaskets and clamps should be utilized When it is expected that flow will be intermittent the meter should not be mounted at a low point in the piping system Solids which settle or congeal in the meter may affect meter performance In order to achieve optimum electrical signal output from the flowmeter due consideration must be given to its isolation from ambient electrical interference such as nearby motors transformers and solenoids The fluid moving through the flowmeter engages the vaned rotor and swirl present in the fluid ahead of the meter can change the effective angle of engagement and therefore cause a deviation from the supplied calibration performed under controlled flow conditions Turbine meters are constructed with flow straighteners to minimize the affects of fluid swirl and non uniform velocity profiles and are adequate for most installations However it is good practice to maintain a minimum straight run of approximately 10 pipe diameters ahead of the inlet and 5 pipe diameters following the outlet Proper installation of the flowmeter minimizes the negative effects of fluid swirl HP 257 Installation 10 A tvpical flowmeter installation is shown below BYPASS RUN Bypass Valve Strainer Flow Straighener Turbine Flowmeter Blocking Valve Blocking Valve
