Precautions on installation – Meter
The Q4000 is an electromagnetic water
meter designed to provide consistent
and accurate measurement in both high
and low flow-rate environments. With
an unrestricted flow tube, a 10- year
battery life and an innovative flangeless
design, the Q4000 is ideal for a wide
variety of bulk flow metering applications,
such as network management, leakage
monitoring and commercial billing.
•
When installing the meter outdoors, provide
shade to prevent exposure to direct sunlight.
•
Do not mount the meter with its display
surface facing downwards.
•
Avoid installing the meter in a very high
temperature environment as this will shorten
the battery life.
•
Provide clearance around the meter pipe
section for piping work. Provide clearance
(30cm or more between pipe edge and floor)
for turning a box wrench, particularly under
a meter pipe section which has lower side
bolts and nuts that are difficult to tighten.
•
Do not install the product in an area affected
by strong electromagnetic field. Select a
location 3-6 feet or more away from the
following: power line, transformer, electric
pump, or motor. Do not install the product
at a point immediately below high voltage
transmission lines, in the vicinity of other
electromagnetic flow meters, or near other
equipment that generates a significant
magnetic field (such as electrified rails).
•
Do not install the product in a place where
stray electrical current is flowing. Electrolytic
corrosion protection current or a leakage
current from a submersible pump flowing
through the metered water can affect
accuracy or product operation. If such current
is observed, apply grounding mechanisms to
isolate the current from the product.
•
Do not install the product in locations subject
to corrosive agents such as seawater, brackish
water, bleach (or other sources of chlorine),
hydrogen sulfide etc. For unknown soil
conditions, consider use of a sacrificial anode
kit. Exposure to strong corrosives may
invalidate warranty protection.
•
Do not install the product in a location
subjected to continuous vibration.
•
Observe the provision for submergence depth
when installing in flooded chambers.
