Questions about this item

How often will the 3000mAh Ni-MH pack need replacing in a PT878 flowmeter?

The pack is rated for one year of service; plan replacement around that interval for reliable operation.

What runtime limit appears first during continuous flowmeter use?

Capacity of 3000mAh at 6.0V delivers 18.0Wh, so total energy stored sets the endurance ceiling.

How much heat does the 428.0g battery generate during all-day measurement sessions?

Normal operation stays within the certified UN38.3 and RoHS thermal limits; no active cooling is required.
