Coltraco Permaflow

Description

The Permaflow is a fixed, clamp-on flow & heat meter. It uses complete non-invasive technology meaning sensors can be positioned on the outside with no need to drill holes or adapt the system in any way, reducing cost, downtime and increasing ease of setup. Being a very flexible platform with numerous bolt-on options, accessories and applications, it offers an ideal solution for measuring the flow rates of most liquids with gas/solid content less than 10% of volume.

Fixed ultrasonic flow meter features

VERSATILE
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

ACCURATE
Capable of measuring flow velocities between 0.01 m/s – 25m/s. Resolution of 0.25mm/s

RELIABLE
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

LOW COST
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

Key benefits of ultrasonic flow meter

ACCURATE
Accurate to +/- 0.5% under ideal conditions. Repeatability of 0.15% of measured value

MONITORING
24/7 flow rate monitoring and alert is available

ROBUST
Sensors rated IP66. Sensor temperature range -20°C to +150°C

INTUITIVE
Unique Human Machine Interface (HMI) driven menu emphasises userfriendliness

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

COMMUNICATIONS
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

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

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

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