What is a fire suppression system?

Fixed fire special fire suppression systems protect urgently important infrastructure against hazards, fundamental for the safeguarding of critical facilities. However, gaseous extinguishing systems leak because they are active and dynamic systems and this threatens the consistent and reliable safety that they should offer to the space that they protect.

What is the method?

Choose the flagship handheld ultrasonic level sensor: Portalevel® for fire suppression system testing in 30 seconds. See the intro video here: https://youtu.be/8XaG7oM5aHA

How does it work?

This innovative technology is designed to be very easy to use. Watch this “how to” video here: https://youtu.be/KpScT_esxnc

What agents does it work on?

The Portalevel® level ultrasonic sensor can inspect CO2 fire suppression system, FM-200™, Novec™ 1230 fire suppression, FE-13™, FE-25™, FE-36™, Halons and a range of other extinguishing agents.

Why is it better?

It is safer, faster and cheaper to check if any gas is left in the bottles with an ultrasonic level measurement sensor. Plus, it is accepted by regulations as an alternative method.

Why is it safer?

Increase fire safety as there is no need to turn off the clean agent fire suppression system during inspection. No need to remove the cylinders from the manifold. Portalevel® level gauge enables you to test in-situ. Plus, no risk to personnel who may suffer back injuries by lifting heavy high pressure cylinders.

How is it faster?

Traditional weighing takes 2 people 15 minutes per cylinder. Portalevel® shows the level with just 1 person 30 seconds per cylinder.

How is it cheaper?

Saving you time so you can carry out more level detection inspections. Saving you labour costs and removing the risk of injuries. Plus, Coltraco Ultrasonics have a “Price Promise” for the most competitive quotes.

How do you calculate the weight of liquid?

If you want the weight of agent as well as the contents verification, you can use the Portalevel® MAX’s perfect partner: Portasteele® CALCULATOR liquid level to weight conversion calculator app to convert readings – taking just another 30 seconds. The clean agent calculator is the ideal tool to save time and money.

This tablet based advanced volume to mass calculator application is the first in the world to provide agent weight readings without physically weighing the cylinders to comply with regulations. It is the ideal FM200 and CO2 Fire Suppression Calculator. With this fire suppression conversion calculator, clean agent calculation is quick and simple. The smart device has a FM200 calculation program built into it, as well as other extinguishing agents such as CO2, NOVEC 1230 and Halon 1301/1211.

Portasteele® CALCULATOR provides instant real-time results which can be recorded then emailed directly for datalogged audit trail. By replacing the use of manual calculation and formulae, Portasteele® CALCULATOR makes the whole process of fire suppression system servicing simple and effective. This is a safer, more efficient and cost saving method to service fire cylinders. The technological innovation ensures an entirely user friendly and industry leading device.

Does the Portasteele® CALCULATOR take into account temperature?

The calculation provided takes into account all environmental factors, such as temperature measurements, without requiring an overwhelming excess of information from the user and can provide highly accurate results across the broad range of cylinder types available in the fire protection sector. The Portasteele® CALCULATOR takes into account temperature variation by compensating for it using density changes. The final result is weight, which is unaffected by temperature – something that cannot be achieved by a liquid level indicator alone.

Can I export my fire suppression system weight results?

The Portasteele® CALCULATOR exports data digitally in a ready-to-use into .csv format. Users can deliver premium reports quickly and easily, whether it is to their office or to their customers.

Why choose a liquid level indicator VS. A built-in magnetic gas bottle level indicator?

There are some limitations to built-in magnetic gas level indicators. They are invasive as they must be integrated inside the container. They cannot be retrofitted. There is room for human error as it relies on the user feeling the magnetic pull on the tape. Finally, the recording measurements manually in paper is less effective vs electronically recording by time and date as with the Portalevel® range.

Does the Portalevel® range work on containers suffering from a layer of rust?

Yes the Portalevel with work on cylinders in poor condition, with the use of ultrasound gel but it is advisable that the rust be cleaned off as much as possible with a damp cloth.

How does a liquid level gauge work?

Ultrasonic technology is transmitted through the Portalevel® sensor which is placed externally on the container. Ultrasound returns to the sensor and depending on what is present behind the containers’ walls (i.e. liquid or gas), the ultrasound reacts differently. Using the ultrasonic fill level sensor, users are able to non-invasively test containers in situ and is accepted by regulations an alternative method.

How do you calibrate an ultrasonic level transmitter?

Like an annual MOT on your car, calibrations service your equipment to ensure it is as accurate and reliable as when you first purchased it. In accordance with ISO 17025 for testing and measuring equipment, annual recalibration is recommended for companies complying with this regulation. Calibration can be conducted in our UK office or worldwide ODA Service Centres.

How often should fire suppression systems be inspected?

The below regulations state how often clean agent tanks need to be tested. Using liquid level survey equipment allows for regular and accurate testing of fire suppression systems.

NFPA 2001 Standard on Clean Agent Fire Extinguishing Systems
Section 7.2.3.5: The weight of agent in the containers shall be verified by weighing or other approved methods

NFPA 12 Standard on Carbon Dioxide Extinguishing Systems
Section 4.8.3.5.1: Container contents checked every 6 months

ISO 6183:2009 Fire protection equipment — Carbon dioxide extinguishing systems for use on premises — Design and installation
Section 9.2.1.3: Loss in CO2 quantity of more than 10% mass shall be refilled or replaced

ISO 14520-1:2015 Gaseous fire-extinguishing systems — Physical properties and system design — Part 1: General requirements
Annex F5: Every 6 months for liquefied gases, check weight or use a liquid level indicator to verify correct content of containers,

BS5306-4:2001 Fire extinguishing installations and equipment on premises —
Part 4: Specifications for Carbon Dioxide systems
Section 9.1.1.3: At least every six months, the container contents shall be checked.

Ultrasonic Gas level indicator project
A project in which the Portalevel® range has been applied is with a well-known Fire Servicing company in the USA who enquired for the Portalevel®, having been recommended our equipment by an associated company. Their interest in the equipment was to see if using a ultrasonic liquid level detector was a viable, accurate and cost effective alternative to testing cylinders by weighing. Two units were purchased for an extensive trial and the Portalevel® was put into operation from their Head Office for a period of 6 months with 2 of their Engineers trained by Coltraco free of charge. After the trial period, the results were clear. Using liquid level gauges for tanks had successfully reduced the time, manpower and cost. Smaller teams are now sent in order to carry out testing with testing only taking around 25% of the time when compared to the methods they were using previously. These cost benefits they were able to pass onto their customers in offering more attractive tender propositions and now the Portalevel® is in use in every one of their 14 locations
