Honeywell’s VersaFlow Clamp-On Ultrasonic flow meter operates using transit time measurement. By measuring the time it takes a sonic signal to travel a known distance with the flow stream and another signal travelling against the flow stream, it determines the velocity of the fluid being measured. With the sonic properties of the fluid and the pipe material factored in, users get an extremely repeatable accuracy on the volumetric flow rate being measured. Because the transmitter can process the signal of one or two sensors, it ensures additional economy and the ability to compare or contrast two flow streams, if required. The product is ideal for users looking for a process measurement device that is easy to install and can maintain flow measurement for clean liquids.
