Fig. 2.1 Unpacking
Caution.
Inspect the flowmeter for damage before installation. Do NOT install a damaged or faulty
flowmeter.
When lifting the flowmeter, use the lifting hooks provided or sling under the body of the meter.
NEVER lift the flowmeter by the sensor cable terminal connection box – this will damage the
terminal connection box and invalidate the warranty.
Caution. Do NOT exceed the maximum working pressure marked on the flowmeter.
Fig. 2.2 Spillage
Caution. Do NOT install the flowmeter in an area where a spillage of any substance could damage the
flowmeter.

forces on the flowmeter, for example, vibration.

Caution. Do NOT subject the flowmeter to localized heat during installation. Remember – the flowmeter
is a measuring instrument.

Fig. 2.6 Within Temperature Limits
Caution. Ensure the flowmeter is operated within its specified temperature limits. Use flange seals
made from a material that is compatible with the fluid and fluid temperatures as required.
Fig. 2.7 Straight Pipe Requirements
Note. Ensure the flow direction in the pipeline corresponds to the identification plate. The flowmeter
measures the flowrate in both directions. Forward flow is the factory setting. Experience has shown that,
in most installations, a straight upstream section 3 x pipe diameters in length and a straight downstream
section 2 x pipe diameters in length are sufficient. However, wherever possible, straight upstream and
downstream sections 5 x 2 pipe diameters in length are recommended.
Fig. 2.8 Fluid Level
Note. For accurate and reliable operation, install the flowmeter sensor in a position where it will be
completely full when in operation. The flowmeter will operate when not full, but indicated readings will not
be accurate.

Caution. Do NOT install the flowmeter in a position that will expose it to direct sunlight. Provide
appropriate sun protection if required.

Caution. When burying a flowmeter, ensure it can be found easily if required (for example, mark the
installation position with a post). Installing a protection plate above the meter is also recommended.
Note. For further advice when burying flowmeters, contact the ABB Service Organization.
Fig. 2.13 Cable Routing
Caution. Install all flowmeter cabling neatly. Installation within a conduit is recommended. Install the
cabling or conduit with a U-bend below the terminal connection box height to prevent water ingress into
the flowmeter sensor by capillary action.

Caution. If flowmeters are installed in adjacent pipelines, ensure they are at least 0.7 m (2.3 ft.) apart to
prevent the electromagnetic field from one meter affecting the other.

Caution. For safety reasons and optimum performance, the flowmeter, pipelines and medium must be
correctly bonded and grounded according to regulations.
Do not ground cathodically-protected pipelines to an external earth.

3.2 Cable Preparation (Remote Transmitter Only)
To prepare the cable for connection at the transmitter and sensor terminal blocks:
1. Remove the outer cable insulation and Mylar® wrap.
2. Ensure the drain wire is sleeved.
3. Cut the cable connection wires to the lengths shown.
3.2.1 Sensor Cable Connections (Remote WaterMaster Transmitter Only)
Caution. Maintain Environmental Protection at all times – See Section 3.3, page 17.
Caution.
Make connections only as shown.
Twist the screen wire of D1 / TFE + D2 with the outer screen drain wire and sleeve them green /
yellow.
Ensure the seal and mating surfaces are clean to maintain environmental rating.
Conduit connections must provide cable entry sealing.
Ensure cable glands are tightened after wiring. Do not overtighten the plastic cable glands to
avoid destroying their sealing properties. Initially, tighten finger-tight, then a further 1/2to 3/4turn
using a suitable spanner or wrench.
