attached to the outside of the lens.

Internals

Installation

Position. FTB8000B-Series meters should be installed horizontally with the register up. Vertical mounting will result in some degree of under-measurement and shortened life of the bearings. No upstream straight pipe is required.

WARNING

DO NOT INSTALL meter in overhead Indoor piping or where leakage may cause damage

Caution: These water meters are not recommended for installation in uninsulated suspended ceilings where freezing is possible, or in any overhead indoor piping configurationwhereleakagemay cause damage.

Couplings. Male NPT threaded couplings are included with each meter. The threads on the end of the meter are IPS straight threads one size bigger than the meter size. Though it is possible to thread a standard pipe coupling directly onto the meter for close coupling, the included couplings are much preferable because they provide a union connection for meter service. Be sure to use the included gasket between the end of the meter and the coupling.

Connections. PR and PT sensors are supplied with a color coded output cable (see diagram, page 4). Optional connectors can be ordered to plug directly into a Omega control or LMI metering pump.

Pulse Output. Both PR and PT sensors respond to a magnet that rotates on the face of the meter under the lens. The sensor turns on and off once each time the magnet passes under it. Sensors are designed for electronic control loads, and should not be used to switch power loads or line voltages. See maximum current and voltage ratings, under Specifications.

Maintenance

Omega recommends all service to be performed by an authorized distributor or the factory to maintain the integrity of the protective tamper-proof wire-and-seal.

Inlet Strainer. Clean the strainer yearly, or as required, depending on water condition. Pull out the strainer or backflush the meter to loosen trapped particulates.

Calibration. Meters used for billing or billing exemption may be regulated by state or local authorities. New meters are factory-tested to meet the AWWA C-708

Multi-Jet Meter accuracy specification. Some states require retesting at various intervals, typically eight years for

3/4" meters, six for 1", and four for 1-1/2" and 2". Meters used for control should be tested every 5-10 years. Testing can be done by the factory or local meter shops authorized for this purpose. Please contact Omega before sending meter in for calibration or servicing.
