Tek-Trol - Model TEK-CLAMP 1200A Series -Ultrasonic Clamp On Flow Meter
Tek-Clamp 1200A Ultrasonic Clamp On Flow Meter is designed to measure the fluid velocity of liquid in a full or closed pipe. It is a measurement system which is both easy to install and use. The Tek-Clamp 1200A operates according to the difference in the Transit Time of Flight measured and determines the flow velocity by measuring the travel time of a pulse from one transducer to the next. Flow in the same direction takes less time to travel to the second transducer than flow in the opposite direction. Electroacoustic transducers receive and emit brief ultrasonic pulses through the liquid of the pipe. Transducers are vertically placed at both sides of the measured pipe. Sensors are placed on the pipe and fastened by means of a clamp. The display will quickly show the flow velocity. The Tek-Clamp 1200A can be used for metallic, plastic, and rubber tubes.
