CALORİMETER TYPES AND ADVANTAGES / DİSADVANTAGES

Calorimeters used in heating systems and used to measure the heat energy are basically working with two different method.

1- MECHANICAL HEAT METERS
2- ULTRASONIC HEAT METERS





Mechanical calorimeters work with the principle that water crossed with hitting the turbine and in the meantime turbine speed measurement. The working principle is shown in the figure below.

There are two different types. One of them is the single jet, the system where water enters from a point and leaves the meter at a point. Another is the multi jet model, where water enters the meter from many points and leaves again. Calorimeter with multi jet system provide to more healthy measurement and longer service life.

The other type of calorimeter is ultrasonic calorimetry. Ultrasonic calorimetry has no moving parts. Measurement is provide with the sound waves in the water is delayed. Basically, the ultrasonic calorimeter is always long lasting and healthy, but in dirty systems the ultrasonic calorimeter has the disadvantage about measuring.
