*Specifications are subject to change without prior notice.

The CDT3000 calorie monitor consists of a pitot tube type flow element with a built-in temperature sensor and a differential pressure instrument equipped with root extraction and calorie calculation functions. By inputting an external temperature signal and calculating temperature difference, it indicates and outputs thermal flow and totalized calorie in addition to flow rate. Applicable pipe size ranges from 20 mm to 450 mm.


  • · Easy installation by welding a 20 mm, 3/4 inch socket on exist ing piping for insertion of CDT3000
  • · Simultaneous measurement of both flow and temperature saves your installation cost
  • · Negligible small pressure loss
  • · Selectable from wide variety of flow meter ranges suitable for your applications
  • · Applicable for both horizontal and vertical pipes
  • · By inputting temperature signal on the fluid feed line it allows thermal flow measurement and totalized calorie calculation to serve as a calorie monitor for your energy conservation
  • · Easy to read with a large LCD display
