Model PD696, PD697 & PD698

6 Digit Loop-powered Flow Totalizer/Rate Meters

Precision Digital's new 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.
