§9.1 RH40 Meter and Battery Maintenance
§9.1.A Battery Maintenance and Replacement
The RH40 features a Ni-H rechargeable battery. Therefore, it is recommended to discharge the battery by
leaving the instrument
on
(it will automatically turn
off
after a few minutes) every 3 months.
In between these times, the battery can be fully charged with the supplied AC adapter. To get close to
100% battery power, charge the device overnight.
When not connected to the AC adapter, the battery should last
2 to 3 hours after being fully charged
.
When the device’s battery is no longer sustaining that life, this normally indicates that the battery has
exceeded its product life. The typical product life of a battery is 2-3 years. Please consult the
manufacturer, at [email protected], for replacing the battery pack.
§9.1.B Meter Calibration
Although it is not required for operation, Spire recommends meter calibration approximately once every 2
years for maximum efficiency. Please contact [email protected] for more information. See Section
§8.2 for instructions on sending in meters for service.
§9.2 Transducer Installation Guide
§9.2.A Find the mounting site
A)
Pipe must be full of liquid at the measurement site.
B)
No heavy corrosion of deposition inside the pipe.
C)
Must be a safe location.
D)
The straight run of the pipe must not be shorter than 15D as a general guideline, where D is the
pipe diameter. Insufficient straight pipe length will degrade the accuracy of the results.
E)
The transducer mounting site should be 10D straight run upstream and 5D straight run
downstream.
F)
If there are flow disturbing parts such as pumps, valves, etc. on the upstream, the straight pipe
length should be increased. The disturbance strength of those flow conducting parts will be (from
low to high):
Single Bend
Pipe Reduction / Enlargement
Outflow Tee
Same Plane Multiple Bends
