weight or spring loaded appliances help you
monitor water use to detect theft or leaks
in a fire system. Hersey Detector Checks are
designed for low pressure loss, easy maintenance,
and unobstructed flow through the main line.
Each one is built to last. Bypasses are available
with Hersey Positive Displacement or Vertical
Turbine Meters. Put a lock on water theft
and leaks with Hersey Detector Checks.
