Zone 1 Ultrasonic level indicator

Overview

The Portalevel® IS is a specialist intrinsically safe ultrasonic liquid level indicator designed for testing liquid contents inside fire suppression systems, in explosive atmospheres. With approval from Ex Veritas, the device is ideal for testing the cylinder contents of fire suppression systems in hazardous areas.

Intrinsically Safe Ultrasonic Level Indicator – Fire Safety in Hazardous Zones

  • Approved to Zone 1, II 2 G Ex ib IIA T4 Gb standard, the Portalevel® IS is capable of working even in the most sensitive of environments.
  • Its primary function is to detect the liquid level in fire suppression cylinders including CO2, FM200™, NOVEC 1230® and all other fire suppression agents, where the systems are installed in ATEX Zones.
  • Critically, this removes the need for inspecting fire systems using a Hot Work Permit and offers significant time, cost and safety benefits when compared to weighing.

Accurate, Easy to Use and Low Risk

  • Powerful Testing: Due to the low power requirements of ATEX Approval, the unit has been evolved to have 3 different Calibration bands and 4 different power levels.
  • Flexible: The Calibration bands allow the unit to set itself up on a wide variety of different cylinder types with minimal input from the user.
  • Accurate: This is critical in maintaining high levels of accuracy (+/- 1.5mm), ease of use and low risk of user error during testing. The different power levels then allow for testing much larger or corroded tanks.

Maintain fire safety in safety critical areas 

If you are maintaining fire suppression systems to identify cylinder contents of liquefied agents e.g. CO2, clean agent etc, in areas where you require Zone 1 instrumentation, you should use the Portalevel® IS. Our intrinsically safe Ultrasonic Level Indicator is safer than weighing. It is the only ExVeritas approved Portalevel® model available from Coltraco Ultrasonics

Intended for use in areas where an explosive atmosphere is likely to occur in normal operation and must ensure a high level of protection. Examples of these areas are environments with gas, vapours and mists (IECEx Zone 1) such as:    

  • LNG Tankers
  • Offshore Platforms with flammable gases
  • Breweries
  • Chemical plants
  • Petrochemical
  • Hazardous material storage facilities
  • Automotive paint booths
  • Gas plants and facilities
  • Aircraft hangers
  • Fuel servicing areas

What's in the box

Portalevel® IS ultrasonic liquid level indicator main unit. 

Ultrasonic gel ssists perfect contact between sensor & testing surface for maximum accuracy and ease of use.

ATEX piezo electric transducer fitted with magnetic applicator allowing for perfect placement of the sensor each time 

Carrying case for ease and safety of transport, delivery and storage 

How to use

Connect the main unit and sensors & turn on

Wet the surface if cylinder in good condition or apply thin strip of gel down the cylinder if required

Identify the region on a cylinder with consistently high readings. Place sensor on a typically high reading and press CAL

The bar braph will now go to 100%. Full bar graph means gas. No bar graph means liquid

Move sensor down the cylinder in 5cm increments, watching the bar graph. When the bar disappears, you have reached the liquid

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.
