Clamp-on fixed ultrasonic flow & heat meter

Overview

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

      • ACCURATEAccurate 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

Frequently asked questions

What materials can the Portagauge 5 test?

The portable ultrasonic thickness gauge can test any type of metal and most hard plastics. The most popular metals include steel, aluminium, copper and popular plastics include PVC, Polyethene and fibreglass to name a few!

How accurate is the Portagauge 5?

The Portauage 5 is accurate at testing true material readings (ignoring surface coatings) to within 0.01mm

How to test sprinkler pipes?

The Portaguage 5 can be used to test any sprinkler pipe or other metal piping to identify areas of corrosion, locations where there has been considerable erosion, areas of fungal deterioration and other forms of metal ware. The testing process involves carrying out a series of spot checks along the bottom of the pipe. It is on the bottom of the pipe where liquid will naturally pool and thus where you are much more likely to have areas of heavy corrosion. The user simply goes down the entire length of the sprinkler pipe and continually monitors the pipe thickness and the waveform. Both should be consistent along the full length of the pipe. As soon as the thickness or the waveform begin to deviate significantly, (and they will normally do so together) the equipment has identified an area likely to be compromised and thus further physical & visual inspections will be required.

Do I need training to use the Portagauge 5?

This equipment is incredibly easy to operate, and no dedicated training is required in order to use the unit. We provide operating instructions which is normally enough to provide an operator with confidence and the required knowledge. However, every Coltraco unit comes with free technical support for the lifetime of the equipment so if you do need any further assistance, our technical team are on hand to support

How long does it take to deliver the portable thickness gauge?

These units are almost always available ex stock from the UK. Delivery to the UK is normally next day, Europe in 2 – 3 days and most of the rest of the world in 3 – 4 days from order. Please contact our sales team for an update on availability and for any other questions.

I don’t need to ignore the paint layer. Will this still work for my needs?

The short answer is yes and normally triple echo thickness gauge technology can be used for any thickness measuring applications. We do also offer our Portagauge 3 technology however which uses single echo technology and will measure paint & material as one reading.
