Low-inertia turbine flowmeter measures refrigerant streams
Titan Enterprises
This company has added a high-pressure version to its 900 Series turbine gas flowmeters (photo), which are designed to track refrigerant flow. Designed with steel-reinforced polymer components, it provides a pressure rating of 40 bars. The low-inertia turbines of the 900 Series flowmeters are ideal for measuring the flow of volatile refrigerant liquids with low viscosity (0.3 to 0.4 centipoise). The device provides pressure drop that is low enough to prevent gas breakout and ensure reliable flow measurement, says the company. The turbine floweter is designed to give±0.1% repeatability across six flow ranges from 0.05 to 14 L/min. Its chemically resistant components make it suitable for an array of fluids, for temperatures ranging from –25°C–125°C. The precision turbine rotates freely on sapphire bearings and contains ceramic bearings that are detected through the chamber wall by a Hall effect detector, explains the company. — Titan Enterprises, Dorset, U.K.
