Clamp on flow meter is a flow meter that is very cheap and easy installation, because it does not have to damage the pipe designed for applicationswhere production should not be stopped, because the installation of flow meters is done with puncture, cut and weld pipe. It is ideal for process measurement in applications where users previously had not installed an in-line flow meter and for applications where large line sizes or exotic materials are required for in-line measurement technologies.
Clamp on Ultrasonic flow meter use Transducers that clamped on to the outside of the pipe so it is not necessary to cut pipes or stop flow for installation and there is no pressure loss. Clamp on Ultrasonic flowmeters can measure various types of liquids such as potable water, river water, industrial water, agricultural water, waste water, seawater and pure water. Ultrasonic Clamp On Flow Meter can be applied to measure the fluid flow in all pipe sizes and types of materials like carbon steel, Stainless steel, HDPE, PVC and other. Clamp on flow meter should be capable of maintaining accuracy in working in conditions where there are temperature fluctuations in the process and the surrounding environment.
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 clamp on ultrasonic flow meter is ideal for users looking for a process measurement device that is easy to install and can maintain flow measurement for clean liquids.
Temporary applications are mainly offered using portable type meters and permanent types are mainly designed for fixed installations. Portable types generally have a memory log or data logging capability to record data and the types designed for permanent applications normally don’t have the recording or data logging capability. However certain types like the Sitelab SL1188 or SL1168 provide a toolbox for logging purposes and to aid in identifying some transitions or abnormal errors during abnormal flow conditions.
