Digital's new loop-powered flow rate totalizers allow you to display flow
rate and total just about anywhere you want. First, there's no AC or
battery power to worry about because these meters are completely
loop-powered. Second, lighting conditions don't matter because LCDs work
great in bright sunlight and the optional loop-powered backlighting works
great in dimly lit areas. Third, there are three types of enclosures to
choose from: Standard 1/8 DIN Panel Mount, NEMA 4X, and Explosion-proof.
The PD698-N-EX and PD698-B-EX have been FM, CSA and CENELEC approved as
explosion-proof as complete products- not just the enclosures.
