Do flow meters use batteries?

Some flow meters use batteries as a backup source of power in the event the primary power source is unavailable. In cases such as these, maintenance procedures will also include a regular examination of any power connections and the standard electrical components along with frequent battery tests.

How accurate is a battery powered flow meter?

Typically, calibration procedures associated with maintenance for battery powered flow meters are based on the unit under test set to a level of accuracy that is four times more accurate than required. During the calibration procedure, the rate of flow must remain in a steady.

How does a flow meter work?

After as battery power is applied. TOTALISER FUNCTION The flow meter has a built in totalising function. The volume of water that has passed through the flow meter is totaled and stored in internal memory. Put the meter readout into totaliser mode by pressing the M (mode) switch once.

How long does a flow meter battery last?

However, batteries do not last forever, either requiring regular charging or replacement. This makes monitoring the remaining power and changing or charging the battery as needed critical. Typically, the batteries are easily accessed, as these flow meters are often installed externally on the pipe being monitored.

How do you store a flowmeter?

Transportation During shipping or transporting of the flowmeter, avoid exposing the meter to strong shock or vibrations or impact. Avoid scratching the rubber liner inside the pipe. Storage If possible, store the meter in its unopened packaging until actual installation. Avoid storing the meter outdoors for an extended period of time.

What happens if a flow meter loses power?

In cases where power is lost in other areas of the facility, the flow meters source of electricity is unaffected. However, batteries do not last forever, either requiring regular charging or replacement. This makes monitoring the remaining power and changing or charging the battery as needed critical.
