10 INSTAATION CONDITIONS 1. piping instructions (for ±.35% RD class) For the design performance of EX Turbine, it is necessary to obtain uniform flow pattern of metering fluid upstream and downstream of the meter. The following piping arrangement guidelines should be observed depending on your desired linearity (within ±.15% or ±.35%). When controlling the linearity within ±.35%, use OVA flow straightener or use the specified straight pipe (compliant with API Chapter 5 Section 3). No. Piping Arrangement Straight Pipe ength () D = Nom. size Remarks 1 OVA s flow straightener Honey Vane S Honey Vane 8D Refer to Honey Vane on page 11. Applicable to Nom. size >25mm Straightener 12D Refer to GS.No GCF1. 2 Reducer 15D min. A concentric reducer is upstream of the meter. 2D min. An elbow is upstream of the meter. 3 Elbow 25D min. Two elbows are vertically upstream of the meter. 4D min. Two elbows are horizontally upstream of the meter. Opened 4 Fully open valve 15D min. A fully open valve is upstream of the meter. Partially Opened 5 Partially open valve 5D min. A partially open gate valve, sharp orifice, or something that markedly disturbs the flow pattern is upstream of the meter. Notes 3: 1) Sch.4 pipe is used as the standard material in the list. Therefore use Sch.4 pipe as the standard pipe. 2) Downstream of the meter, be sure to install 5D straight pipe. 3) Pressure or temperature detector shall be located downstream of the meter as shown in Fig. 3.

11 2. Requirements of backpressure for EX Turbine As the flow velocity increases in EX Turbine, cavitation could be produced. By cavitation, a meter error could also shift to + side and fluctuate considerably. In order to prevent this, it is required to maintain a constant backpressure. Thus, API-MPMS Chapter 5 Section 3 specifies the required of backpressure in the following equation: PB 2ΔP Po (MPa [absolute]) P B : Back pressure (Pressure at downstream pipe outlet) ΔP : Pressure loss (MPa) Po : Vapor pressure of liquid to be metered. (MPa [absolute]) 3. Strainer Install a strainer upstream of the meter to prevent the meter from damage with foreign solids. Where nominal size of EX Turbine is smaller than the piping nominal size, select a strainer having the same diameter as that of the pipeline. (Usually, flow velocity in a strainer should be controlled to less than 4 to 5m/sec and the pressure to less than 29.4kPa). Nominal sizes and net mesh are specified as follows: 5. Air Eliminator If any quantity or bubble is present in the liquid, metering error could considerably increase being not negligibly small. For this reason, installation of OVA air eliminator upstream of the meter is recommended. 6. agging (heat insulation) Work If heat insulation is considered for the piping, simplified lagging (without mortar finish, for example) is suggested for areas where the turbine meter is installed to facilitate disassembly and inspection. Such considerations will permit removing the flowmeter connecting bolts without the need of breaking the coat of lagging material each time at servicing.
