Permaflow® Complete Package-3578010-FLOW

New February 2021
Fixed, clamp-on, ultrasonic transit time flow and heat meter
Measure and monitor volumetric flow rate, mass flow rate, energy (heat quantity) flow rate – from one instrument

Product Description

Fully non-invasive (no drilling required) for measuring the flow rates of most liquids with gas/solid content less than 10% of volume, with 4 – 20 mA outputs and PT100 thermometer integration

Non-invasive (no drilling required) for measuring flow rates of most liquids with gas/solid content less than 10% of volume


Built-in signal oscilloscope for sensor positioning and diagnostics to achieve maximum accuracy with the measurement while providing visibility of the potential issues


Connection to PC available as standard using both RS232 and built-in USB as well as 4 – 20 mA inputs which is available as an optional plug in


All measured values can be totalised giving total flow rate measured during a particular measuring session


Commercial building heat metering, fuel montoring, waste water and many more


Ability to incorporate PT100 thermometer inputs so heat quantity measurement can be monitored alongside flow rate


    Capable of working on pipes DN15 – DN 2500; virtually any clean liquids; on a wide range of pipe materials. Without contact with the fluid, there are also fewer issues with the flowmeter being damaged by the nature of the fluid it is measuring compared to inline flowmeters
    Capable of measuring flow velocities between 0.01 m/s – 25m/s. Resolution of 0.25mm/s
    Wall mounted and fixed therefore suitable for conducting measurements in a wide variety of poor conditions as the equipment is affixed firmly to the wall
    No installation costs such as drilling into pipes, therefore no downtime to the pipe network is present. Only one individual is required to operate the instrument


  • ACCURATE: Accurate to +/- 0.5% under ideal conditions. Repeatability of 0.15% of measured value
    24/7 flow rate monitoring and alert is available
    Sensors rated IP66. Sensor temperature range -20°C to +150°C
    Unique Human Machine Interface (HMI) driven menu emphasises user-friendliness
