Titan Enterprises Ltd., an international manufacturer of flow meters, has proposed an optical flow sensor technology to monitor the flow of coolant to the world’s largest optical telescope, the 10.4-m Gran Telescopio Canarias (GTC).

After attempts to use turbine and ultrasonic flow sensors proved unsuccessful due to metallic film build-up on the propellers and microbubbles in the coolant of GTC’s hypersensitive astronomical camera, known as HiPERCAM, a team at Titan Enterprises proposed the Titan FT2, an optical flow sensor that uses an LED and photodiode and is impervious to the undesirable characteristics of the telescope’s cooling fluid.
