This consists of a number of calibrations at various fluid viscosities which cover the range of interest. Data resulting from all the calibrations are presented as K-factor, Meter Factor or Error as a function of flowrate (or frequency) divided by kinematic viscosity. This ratio can be written Q/ν.

5 Pressure Drop Pressure drop across the HELIFLU Flowmeters is approximately 3.6 PSI at maximum flowrate with a relative density of 1 (API gravity = 10) and a kinematic viscosity of 1 cst. The pressure drop at any flowrate Q, for kinematic viscosity ν and relative density d can be calculated from : Delta P (PSI) P = with: P d ν Q : Pressure drop (PSI) : Relative density : Kinematic viscosity (cst) : Flowrate (Bbl/h) : Maximum flowrate (Bbl/h) Viscosity (cst) HELIFLU Flowmeter Configurations The HELIFLU Flowmeter can be installed either horizontally or vertically (flow upwards). The diagram below represents a typical design of a flowmeter assembly and its related equipment. Qmax 3.6 x d x ν 0.2 x Q max Coriolis mass flow meter PD meter Traditional turbine meter HELIFLU TM meter Meter run 10.D 5.D ( Q )2 Back Pressure For non LPG fluids, the numerical value of the minimum absolute back pressure should be estimated from the equation : Pback 2 x P X Pv í with: Pback : Back pressure P : Meter pressure drop at max. flowrate (+ Flow conditioner) P v : Vapor pressure at Max. temperature Pressure drop through the meter is proportional to the square of the flowrate. For a constant inlet, there is a maximum flowrate at which a turbine meter can be operated within acceptable error limits before performance deteriorates. This is due to cavitation effects. It will be noted that the lowest pressure occurs within the rotor and it is here that the cavitation may occur. This will be indicated by a sudden change in meter factor and is more likely to occur with a vapour pressure fluid with a low system operating pressure. Mounting the meter in a vertical orientation with flow from the bottom to the top will not impact the meter factor. When the flow range is too great for one meter or its prover, a bank of meters can be installed in parallel. Each meter in the bank shall operate within its minimum and maximum flow rates.
