The VARIOTEC 480 EX range gives network technicians an efficient and cost effective means of carrying out all common measurement tasks in gas distribution networks.
The 480 EX and 460 EX can incorporate an optional ethane detector to quickly distinguish between natural gas (methane) and swamp gas. No more false indications from swamp gas rather than natural gas.
All variants, (except for the VARIOTEC 400 EX), can have optional oxygen and carbon monoxide sensors fitted.
VARIOTEC 480 EX Features
- Unique and simple to use operating system, with jog dial, soft keys and easy to follow task orientated menu navigation
- Large matrix display with backlight, clearly showing all gas levels
- Rapid charging in 4 hours – More usage time
- Power supply via 4 AA rechargeable or disposable batteries
- On board data logging with PC communication via USB port
- The carrying handle doubles as a clever display stand allowing versatile positioning and easy carrying.
VARIOTEC 480 EX - Efficiency
- Simple, task orientated menu structure means new users are up and running with very little training
- No complicated setup required even after extended periods of disuse
- Cost-effective operation thanks to low capital cost, high up time, low maintenance costs, and paperless inspection regime
VARIOTEC 480 EX - Measuring technologies
- Fast and highly-sensitive semiconductor sensor for measuring very low gas concentrations in the ppm range
- Electrochemical sensors for measuring oxygen and carbon monoxide (optional)
- Integral gas chromatograph to measure ethane. This differentiates between natural gas and swamp gas without any other accessories (optional)
Applications:
Inspection above ground
Measuring low gas concentrations above ground and above gas pipes.
Example: Inspection of underground gas pipes
House
Measuring low gas concentrations in buildings and locating the source of gas leaks.
Example: Leak detection in accessible gas installations
Work area monitoring
(Warning EX and Warning ExTox)
Monitoring and protecting the work environment, property and personnel during work on gas pipes and/or gas installations where there is a risk of explosion.
Example: Work on gas pressure regulating stations, biogas plants, responding to reports of the smell of gas
Enclosed spaces
Measuring gas concentrations in enclosed spaces where there is increased potential of gas build up.
Example: Telephone switch boxes, lamp posts, sewers
Measuring in bar holes
Measuring the gas concentration and determining gas dispersal in the ground, leak classification and location of suspected gas leaks.
Example: Reducing the area of leak search
Gas purity measurement
Proving gas purity / absence of natural gas and or oxygen in gas pipes.
Example: Decommissioning and recommissioning of gas pipes
Ethane analysis
Determining the methane, ethane, and propane components of a gas sample
Example: Distinguishing between natural gas and swamp gas if a leak occurs
Ethane analysis – Natural gas or swamp gas?
The VARIOTEC® 480 product family helps the user pinpoint leaks in underground pipes.
Before making an expensive excavation you need to be sure the gas detected is really emanating from a natural gas pipe and that it is not swamp gas or coming from another gas source.
The optional integrated ethane detector can quickly and easily distinguish between natural gas and swamp gas. There are no accessories or any specialist training required. The user is guided through the ethane analysis process with clear prompts. The result can then be saved and stored on a PC for record keeping.
Ethane analysis – Accessories
- Charging equipment for 12 V, 24 V or 230 V
- Docking station/wall bracket
- System case
- Testing equipment and test gases
- Flexible hand probe with probe hose
- Localisation probe
- Bell probe
