  • OMEGA™ FTB-201 Series turbine meters have male flared-end fittings for easy connections. They are built to meet the performance requirements of MS 33656, though they do not carry a militaryspecification. These units come with a mating 2-wire connector and can be supplied with the integrallymounted signal conditioners (Please see the FLSC-18B Series for more information) to provide 4 to 20 mA, 0 to 5V, and factored pulse outputs.

    Flow Straightening
    Proper application of a turbine flowmeter requires that there be a suitable piping section both downstream and upstream of the meter if it is to achieve optimum accuracy.Whereas an inlet straight pipe run of 10 pipe diameters and an outlet straight pipe run of 5 pipe diameters provide the necessary flow conditioning in general, some applications require an upstream flow straightener.Such applications include custody transfer.A flow straightener consists of a section of piping which contains a suitably dimensioned and positioned thin walled tube cluster to eliminate fluid swirl.(see full specifications for "Typical Turbine Meter Installation Drawing".

    37° Flare Installation Kits
    Installation kits with the required up and downstream straight pipe lengths for proper turbine operation are available.Installation kits for turbine meters with 37° flare end fittings consist of two lengths of stainless steel tubing cut to a length appropriate for the upstream and downstream straight pipe runs and flared at one end.Mating sleeves and nuts are included.The kits can be conveniently butt-welded into the piping system.Flow straightening sections may be provided with the installation kit. Kits are available in tubing sizes from ½ to 2 ½".

    Strainers and Filters
    Turbine meters are intended for clean fluid service only; where there is any doubt concerning possible particulate impurities in the process fluid, strainers are recommended.A strainer/filter may be required to reduce the potential hazard of fourling or damage that can be caused by foreign matter.Pipe rouge, the extremely fine rust which develops on the inside of some piping, is a serious problem for turbine meters, due to the difficulty in filter out these particles.Consult Omega Flow Engineering Department for applications that may entail pipe rouge.

    When using FTB-200 Series units for fluids with viscosities other than 1 centistoke, special calibrations and universal viscosity curves are available, consult OMEGA’s Flow Engineering Department for quote.
