Hydrometer Internal Components Hydrometer Internal Components (Double Chamber Not Available in 6”) 12 • Hydrometers Operation and Maintenance Manual
Installation A. Installation Requirements • Globe configuration hydrometers require no straight pipe installation requirements. Do not install valves that will cause a restriction directly upstream or downstream of the hydrometer. • Connections to the hydrometer should be the same size as the meter. Example: if a 3” hydrometer is installed, 3” pipe and fittings should be connected to the hydrometer. • Prior to installation of the meter, the pipeline should be thoroughly flushed. • Recommendation: Air Vents of proper size and type, Continuous acting and large acting, be installed to eliminate air. B. Unpacking The hydrometer comes fully assembled according to the customer’s specifications. The 1½” model is shipped with the appropriate couplings and gaskets. For larger diameter models installation hardware is not included for larger diameter models. Pilot valves and other accessories are factory installed and calibrated according to the customer’s specifications. C. Pipeline Installation The following tools are required to perform these procedures: • Flat blade and Phillips head screwdrivers in various sizes • Open end or box wrenches in various sizes • Large pipe wrenches • Pliers • Dies or pipe threading tools compatible with the pipeline diameter • Teflon tape or similar pipe sealing material D. Preliminary Steps 1. Before beginning the installation, the line should be thoroughly flushed to remove any foreign matter. 2. Close the inlet valve in order to shut off the water flow to the pipeline. E. Installing 1½” and 2” Models The 2” hydrometer can be attached directly to a male threaded pipeline or to a female threaded pipeline using a coupling. The 1½” model can only be attached using a coupling. Coupling Connection • Create a female threaded connection on both pipe sections. • Apply Teflon tape or similar material to seal the connections. • Insert the male coupling connections into the pipeline sections and tighten securely. • Place a coupling gasket over each male threaded hydrometer connection and securely tighten the coupling nuts. Direct Connection • Create a male threaded connection on both pipe sections that are to be attached. • Apply Teflon tape or similar material to seal the connections. • Insert the male threaded pipe connection into the hydrometer and tighten securely. F. Installing 3” – 8” Models The end user is expected to supply the appropriate gaskets and bolts according to the diameter of the pipeline. • Place the appropriate gasket onto each flange. • Insert the bolts, nuts and washers and tighten securely.
