TURBINE FLOW METERS

Turbine flowmeters measure liquid, gas, and steam flows by detecting the rotational velocity of a turbine rotor in the flow stream. The rotational velocity of the turbine rotor is directly proportional to the fluid velocity flowing through the turbine. In Pro-T® turbine flowmeters, the turbine blade movement is detected magnetically, with each blade generating a pulse measured by an electrical pickup. This local fluid velocity is used along with other parameters such as pipe size and Reynolds Number to calculate the average fluid velocity in the pipe. With the average fluid velocity and area of the pipe known, a volumetric flow rate is calculated.

With optional integrated temperature and pressure sensors, Pro-T turbine flowmeters can provide a compensated mass flow rate. With the energy monitoring option, Pro-T meters can also provide a reliable (BTU) energy measurement of water, thermal oils, and steam.

Insertion style turbine flowmeters are a more economical option on large line sizes and can be installed under full process conditions (hot tapping).
