PERMAFLOW
Fixed, Clamp-on, Transit Time Ultrasonic Flow Meter PERMAFLOW
The Permaflow® is a fixed, clamp-on, ultrasonic transit time flow and heat meter that is non-invasive for measuring the flow rates of liquids containing less than 10% of gas/solid contents.
It is mains powered, designed for 24/7 monitoring and is accurate to +/- 0.5% of measured value under ideal conditions.
The system is built with modular I/O modules, with a range of different options available, allowing you to choose only what you need to save you cost and money. It comes with USB and RS232 as standard for serial communications and 16MB internal memory. It is capable of saving measurements internally, to be exported later to a PC, or data stream directly from the system to the PC. To help to achieve reliable measurements, the system comes with built-in oscilloscope for signal diagnostics that assists you in performing a reliable measurement as part of the setting up process.
Suitable for commercial
building heat measurement, fuel monitoring, wastewater, etc.

- Clamp-on design eliminates installation costs such as drilling into pipes and avoids downtime for the pipe network.
- Provides 24/7 flow rate monitoring with customizable alert options.
- No contact with the fluid being measured, eliminating the risk of pressure loss throughout the pipe network.
- The fluid cannot damage the flowmeter, contributing to a longer lifespan and lower maintenance costs compared to inline flowmeters that are in contact with the fluid and risk damage from pressurized flow.
- The Permaflow® can be wall-mounted or fixed for a stable and neat installation, ensuring the display and measurements are clearly visible in various room conditions.
