Portaflow Hand-held Flow meter
Fuji Electric Portaflow
This Fuji Electric Portaflow, portable ultrasonic flow meter consists of a compact, lightweight flow transmitter and a pipe-mounted sensor. Featuring the latest electronics and digital signal processing technology, it provides accurate measurement while being easy to use.
It offers a wide range of applications thanks to its ability to adapt to all types of conditions and a wide choice of liquids and pipe sizes.
Application examples: leak detection of any liquid in a pipeline, temporary measurement of liquid flow for maintenance purposes in pipes of any size, volumetric flow in clean liquids and those with small amounts of suspended solids or aeration such as surface water or raw sewage, non-invasive flow calibration of an existing electromagnetic flow meter, pump flow control and district heating network measurement and balancing.
Features of Fuji Electric Portaflow

Portaflow Consumed Energy Calculation
A function to obtain thermal energies exchanged via fluid used in air-conditioning systems. The transmitter calculates the consumed thermal energy based on the forward flow temperature, the return flow temperature, and the flow rate.
