Used in

Common applications for GEMS SENSORS
Cooling water systems — Gems Sensors flow sights with remote output (e.g., 1AMB2) monitor flow to critical equipment and signal alarms.
Lubrication lines — Gems Sensors flow indicators (e.g., 1AMD3) provide visual confirmation of oil flow to bearings and gears.
Process water monitoring — Gems Sensors flow sights (e.g., 1AMB9) verify flow in water treatment and chemical dosing systems.
HVAC systems — Gems Sensors flow switches (e.g., 1AMB5) detect flow in chilled water and condenser loops for pump control.
Food and beverage — Gems Sensors flow sights with stainless steel bodies (e.g., 1AMD4) are used in clean-in-place (CIP) systems for flow verification.
Power generation — Gems Sensors flow sights (e.g., 1AMB6) monitor cooling water and lube oil flow in turbines and generators.
