Hydrometers Operation and Maintenance Manual • 13

Installation

A. Installation Requirements

• Globe conguration 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 ttings should

be connected to the hydrometer.

• Prior to installation of the meter, the

pipeline should be thoroughly ushed.

• 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 specications. 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 specications.

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

• Teon tape or similar pipe sealing material

D. Preliminary Steps

1. Before beginning the installation, the line should be thoroughly ushed to remove any

foreign matter.

2. Close the inlet valve in order to shut off the water ow 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 Teon 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 Teon 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 ange.

• Insert the bolts, nuts and washers and tighten securely.
