Nilan Comfort CT300 / Polar

The Comfort CT300 / Polar is a versatile digital turbine gas meter designed for residential and light commercial applications. This turbine flow meter measures gas flow rates to determine gas consumption. It provides accurate and reliable gas measurement, helping users monitor their gas usage. The CT300 is an ideal gas metering solution for applications like residential gas meters, commercial cooking gas, natural gas vehicles, gas turbines, and more. In this article, we’ll take a closer look at the features, working, applications, and benefits of the Comfort CT300 / Polar turbine gas meter.

Working Principle

The Comfort CT300 works on the principle of turbine flow measurement. It consists of a turbine rotor mounted on a shaft within the gas flow passage. As gas passes through the meter, the rotor spins at a speed proportional to the gas velocity. The rotor blades then interrupt an LED beam, and these pulses are detected by an optical sensor. The sensor sends the pulse data to an electronic converter, which translates the signals into volumetric flow rate and totalized volume.

The CT300 uses a low-friction ball bearing design that allows the rotor to spin easily with minimal gas flow. This enables it to measure even low flow rates precisely. The rotational speed of the rotor is proportional to the gas flow rate – the faster the rotor spins, the higher the flow rate. This allows the flow meter to measure gas flow across a wide range of flow rates.
