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 do I use the Flowmaster?

Pressure measurements can be made with the flow meter in the OFF position. The Flowmaster is ready to measure flow as soon The Flow meter backlight LEDs will turn on. After as battery power is applied. TOTALISER FUNCTION The flow meter has a built in totalising function.

How do you maintain a portable flow meter?

For portable flow meters with disposable batteries, such as those used in agriculture for monitoring irrigation, this maintenance phase may be as simple as opening the device and changing out a 9-volt battery. Others may be somewhat more complex or can require a different battery type to provide enough power for the device.

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 often should a Flowmaster 250 battery be used?

BATTERy LIFE once per month when the meter is not being used. The type of battery in use on the Flowmaster 250 is Clean the electrodes (especially if the meter has been NiMH type. This battery type is designed for regular but used with oily water) to ensure trouble free operation intermittent use.

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.
