Titan Enterprises low inertia meter for measuring refrigerant flow

Titan Enterprises has developed and is supplying a high pressure version of its 900 Series turbine flowmeter for measuring refrigerant flow.

Adapted with steel reinforced polymer components, to give a pressure rating of 40 Bar, the low inertia turbines of the 900 Series flowmeter are designed for measuring the low viscosities (0.3 to 0.4 centipoises) encountered with volatile refrigerant fluids measured in the liquid form. With careful sensor selection the pressure drop through the 900 Series flowmeter has been designed to be low enough to prevent gas break-out and ensure reliable flow measurement.

The flowmeter is designed to give high performance (+/- 0.1% repeatability) across 6 flow ranges from 0.05 to 15 litres per minute. It's chemically resistant components make it the ideal choice for the metering of a wide range of fluids from -25°C to +125°C. To ensure the highest degree of inertness to metered fluids flowmeter's polymer components are moulded in an FDA-approved grade of PDVF and mounted in a 316 stainless steel body.

At the heart of the flowmeter is a precision turbine that rotates freely on robust sapphire bearings and contains encapsulated ceramic magnets that are detected through the chamber wall by a Hall effect detector. The output is a NPN pulse that is readily interfaced with most electronic display or recording devices. This combination of materials and technology ensures a long life product with reliable operation throughout.
