The FD-Q series clamp-on flow sensor is compatible with a wide range of pipe materials and liquids. The sensor can detect the flow rate of a liquid without the need for pipe modification. The ultrasonic measuring principle enables the detection of a variety of liquids such as water (and pure water), oil and chemicals. The flow sensor is compatible with metal pipes and plastic pipes up to 2″ in diameter and can be installed in-process. Costs are significantly reduced by this minimal installation effort, and the clamp-on mechanism eliminates the risk of pressure loss or increased maintenance effort.
