Handheld, clamp-on, transit time ultrasonic flow meter

The Portasonic® 2.FL0 is a handheld, clamp on, non-invasive ultrasonic transit-time flowmeter designed to measure flow rates liquids in pipes accurate to +/- 0.5% without requiring any invasive installation. It works on a wide range of liquid types containing less than 10% solid content, and pipes from DN15 – DN2500 made from different metal or plastic materials.

Clamp on portable flow meter

Overview

The Portasonic® 2.FL0 handheld ultrasonic transit time flow meter has been tested and calibrated at an ISO 17025 laboratory, capable of meeting accuracies of +/- 0.5% of the true flow rate. We strive to offer the highest quality instruments, built with exceptional quality materials in the UK and remain competitively priced in the market worldwide through our unique R&D position. 

The different types of flow measured by the Portasonic 2.FL0 are:  

  1. Volumetric Flow Rate: such as litres per hour (l/h) or gallons per minute (gpm) etc. 
  2. Mass Flow Rate: such as kilograms per hour (kg/h) etc. 
  3. Heat or Energy Flow Rate: such as kilowatt hour (kWh) or British Thermal Unit (BTU) 

All measured values can be individually totalised giving you the total flow rate that has been measured during a particular measurement session. 

Some of the key advantages of Portasonic 2.FL0 over our competitors: 

  1. BUILD QUALITY: Our ultrasonic flow sensors are made using a special composite material to optimise ultrasound transmission. 
  2. BUILT-IN OSCILLOSCOPE: All units come with built-in oscilloscope for signal diagnostics that assists you in performing a reliable measurement as part of the setting up process 
  3. INTEGRATED THICKNESS GAUGE: Integrated ultrasonic thickness gauge allows you to perform simple NDT testing (ultrasonic thickness gauging) on the wall thickness of your pipe to determine wall thickness and look for signs of corrosion. 
  4. ISO 17025 CALIBRATION: Option to include ISO 17025 calibration certificate to verify the accuracy of your unit, we work closely with an established ISO 17025 flow laboratory in the UK to ensure our equipment meets your requirements 

Some of our main specifications (please see technical specifications below for full breakdown): 

  1. Works on pipes DN15 – DN 2500 
  2. Works on most clean liquids 
  3. Works on a wide range of pipe materials 
  4. Accurate to +/- 0.5% under ideal conditions  
  5. Measures flow velocities between 0.01 m/s – 25m/s 
  6. Resolution of 0.25mm/s 
  7. Repeatability of 0.15% of measured value 
  8. Main units rated IP65 
  9. Sensors rated IP66 
  10. Sensors temperature range -20°C to +150°C 
  11. Battery life up to 12 hours continuous use on a standard 9V PP3 battery for easy replacement 

Main benefits of choosing non-invasive ultrasonic transit time technology over inline flow measurement technology: 

  1. Clamp on, portable and non-invasive which allows a single instrument to be used across multiple different pipes / pipe sections 
  2. No installation costs such as drilling into pipes, therefore no downtime to the pipe network is present 
  3. As there is no contact with the fluid being measured, there is no risk of pressure loss throughout your pipe network 
  4. As with above, the fluid cannot damage the flowmeter, which could contribute to a longer lifespan and lower maintenance cost compared to inline flowmeters which are in contact with the fluid and risk being damaged by the pressurised flowing fluid

Frequently asked questions

What types of fluids and pipe materials will the Portasonic® 2.FL0 work on?

The Portasonic® 2.FL0 works on a variety of different fluid types, as long as the speed of sound in the fluid is known. There is a built-in database of over 19+ fluids ranging from: water, sea water, kerosene, petrol, fuel oil, crude oil, Freon R134a, Freon R22, diesel oil, castor oil, F-76 fuel oil, Novec™ 1230, glycol/water, etc. There is an option to input custom fluid types as long as you know the speed of sound in the fluid – this can be found from online databases

The Portasonic® 2.FL0 will also work on a variety of pipe material, as long as the speed of sound in the pipe material is known. There is a built-in database of over 12+ pipe material ranging from: carbon steel, stainless steel 304, stainless steel 316, cast iron, ductile iron, copper, PVC, lead, nylon, PE, aluminium, asbestos, fibre glass, etc. There is an option to input custom pipe materials as long as you know the speed of sound in the pipe material – this can be found from online databases

What pipe sizes will the Portasonic® 2.FL0 work on? Do I need multiple sensors?

The Portasonic® 2.FL0 will work on pipes ranging from DN15 – DN2500 (1/2” – 98”). It is recommended that you notify us with the range of pipes you will be testing so we can allocate the appropriate sensor type for your application

The Standard Sensors (Model No. DM10) will work from DN15 – DN700 (1/2” – 27”)

The Large Sensors (Model No. DS10) will work from DN25 – DN2500 (1” – 28”)

I am not sure if the fluid in the pipe is full, and whether there are any gas or solid content in the fluid. Will the Portasonic® 2.FL0 still work?

The accuracy and reliability of the Portasonic® 2.FL0’s flow measurement is dependent on your flow profile and how full the pipe is with your fluid

To achieve maximum accuracy and reliability, the pipe needs to be full with the fluid during measurement

The Portasonic® 2.FL0 will work in fluids with up to 10% of gas or solid content. If your fluid contains a larger amount of solid content, a Doppler ultrasonic flow meter may be more suited for the application

Will the Portasonic® 2.FL0 work on painted or corroded surfaces?

If the paint layer is thin and in good condition, the Portasonic® 2.FL0 will work well on the painted surface

If the surface of the pipe is corroded, or the paint layer is thick, it is generally recommended to remove the paint layer before measurement is taken

What are the main benefits of Portasonic® 2.FL0 over inline flow meters?

The Portasonic® 2.FL0 clamps on the pipe, is portable and non-invasive which allows a single instrument to be used across multiple different pipes / pipe sections

There are no installation costs such as drilling into pipes, therefore no downtime to the pipe network is present

As there is no contact with the fluid being measured, there is no risk of pressure loss throughout your pipe network

As with above, the fluid cannot damage the flowmeter, which could contribute to a longer lifespan and lower maintenance cost compared to inline flowmeters which are in contact with the fluid and risk being damaged by the pressurised flowing fluid
