The DP180 comes complete with 3/16 in. O.D. barbed brass pressure fittings, install with 1/4 in. push-on tubing. Both the positive (high) pressure port and the reference (low) pressure port are on the bottom of the unit, labeled high and low respectively. For the best results and shortest response times, use 3/16 in. I.D. for tubing lengths up to 100 ft long, 1/4 in. for tubing lengths up to 300 ft, and 3/8 in. I.D. for tubing lengths up to 900 ft. The static pressure probe is the positive (high) pressure port on the bottom of the unit. Use the reference (low) pressure port on the bottom of the unit for differential pressure measurements.
