A variable current or pulse output, proportional to the detected flow rate, is also produced by the PF220 portable ultrasonic clamp on flow meter to enable it to interface with a range of external control devices such as those found in building management or site monitoring systems. The PF220 portable ultrasonic clamp on flow meter is very much designed with ‘ease of use’ in mind. An interactive Quick Start menu, which simplifies system installation at any suitable location, together with minimal set-up requirements, means that the system can be installed and brought into service very quickly. Furthermore, the application parameters for a particular site can be saved to nonvolatile memory and instantly recalled if a site is revisited for monitoring at a later time – further reducing the set-up time.
The flow sensors, or transducers, connected to the PF220 portable ultrasonic clamp on flow meter are attached to the outside of the pipe being monitored and provide totally non-invasive flow measurement without disturbing the existing plant equipment or process operation.
