Thermal Mass Flow and Level Switches

DELTA M – Thermal Flow or Level Switches

Thermal differential fluid detection technology by DELTA m (Delta M Corporation) is used in the design, and manufacture of thermal mass switches for the detection of high or low flow of liquids and gases, designed and manufactured by. Delta m also manufactures thermal switches for level or temperature detection of liquids or gases.

Flow Monitoring Applications: Pump protection, Cooling Water flow, Analytical Sample Confirmation, Safety Shower Monitor, Hea transfer fluid monitor, Rotating Equipment Lubrication, Safety Relief valve Monitor, Bursting Disc or Rupture Disk Sensor, Flow Confirmation, Oven Exhaust / Air Purge Monitor, Dry line Indication, Soot Blower Feed Water monitor, Chemical Injection Monitor, Vapour Recovery Monitor, Fire Suppression System Monitor, Gas Purge Confirmation, Sanitary Cleaning System monitor.

Level Monitoring Applications: Tank Leak detection, Tank Overflow monitor, Truck and Railcar loading, Reactor / Vessel Charging, Foam control in tanks, Water detection in fuel tanks, Sump Level monitor, Stream trap level control, Interface detection, Immersion heater protection, backup for continuous level monitoring.
