Featuring Darhor’s unique spring loaded variable area design. Darho meters can be installed quickly without costly flow
straighteners or other special plumbing requirements. These meters operate within ±5% accuracy and are constructed
of Polysulfone plastic. Available port sizes range from 1/2" to 2" with a choice of brass, T303 stainless steel or PVC fittings.
Optional Flow-Alert Flow Switch modules automatically signal alarms if flow is too high or too low. The switch options include
AC and DC latching switch modules or a reed switch module.
