Micronics PF222 Portaflow Portable Ultrasonic Clamp-on Flow Meter - Choice of Model

The PF222 Portaflow range brings simplicity to the non-invasive measurement of liquid flow and hydronic energy. Portaflow offers the user quick and accurate flow and energy measurement with its easy-to-follow menu and simple setup. Results can be achieved within minutes of opening the case!

Compact, rugged, and reliable, the Portaflow range has been designed to provide sustained performance in industrial environments.

The PF222 Portaflow electronics are housed in a specifically designed enclosure, which incorporates the graphic display, keypad, sensor, and output facility connections. Set-up of the unit is carried out by selecting the options displayed in the main menu and by following the simple instructions in any of the user-selectable languages.

The use of a rechargeable battery allows the unit to be operated for over 14 hours depending on the facilities used. Continuous operation via the PSU is also possible while recharging the battery. Battery status, signal strength, time and date, as well as flow and energy information, are all continuously displayed, keeping the user fully aware of the measurement process.

How Does it Work?

The Portaflow 222 is a transit time ultrasonic flow meter designed to work with clamp-on transducers, to provide accurate measurement of liquid flowing within a closed pipe, without the need for any mechanical parts to be inserted through the pipe wall or to protrude into the flow system. It takes just a few minutes to install and there is no need to shut down flow or drain the system!

When ultrasound is transmitted between the transducers, its velocity is slightly increased when travelling in the direction of flow, and slightly reduced when travelling against the flow. The resulting transit time difference is directly proportional to the velocity of the flow in the pipe. Having measured the flow velocity and knowing the pipe cross-sectional area, the volumetric flow can be easily calculated.

Hydronic thermal energy, heat, or cooling load is calculated from a combination of the flow rate and the flow and return temperature difference or delta T to comply with EN1434 section 6.
