Description

The GOLIATH is perfectly suited as an LDAR (leak detection and repair) device for the emergency services. In addition to the frequent case of a reported gas odour, a large proportion of cases are based on the statement "no gas present". In this case, the fitter must determine the cause and IS reliant on measuring force in the gas installation. The GOLIATH, with a measuring range of 0 to 2,000 hPa (optional pressure sensor), also perfectly meets this task. In many gas supply companies, it has proven useful to detect carbon monoxide concentrations in addition to monitoring the room air for combustible gases. For this reason, the CO concentration is also displayed and an alarm is triggered from 10 ppm in the case of a "house test". In this way, the operator IS alerted to possible problems with the flue gas ducting.

Features

Time-tested Esders operation concept.
Very quick initial break-in phase after being switching on or changing application.
Extremely short reaction times when measuring CH₄ and CO₂ in all concentrations.
Oxygen and up to 3 toxic gas sensors are available as an option.
Ethane analysis with automatic measurement result assessment can be integrated.
Optional pressure measuring up to 2,000 hPa.

Goliath Option v

Speed measurement
For our gas stand pipe we now offer the possibility to measure the speed when gassing or emptying gas pipelines.

The gas test stand pipe is a proven tool in the field of gas supply, which is used for pressure testing, filling and commissioning of gas pipes. For the gassing of the pipe, the DVGW recommends filling the pipes at a speed of between 3 and 7 m/s in the pipe. We now offer a practical solution for this task. A measuring pipe is used, which is equipped with an internal pitot tube and is connected to the GOLIATH gas measuring device for evaluation.

The GOLIATH Option v is equipped with a differential pressure sensor to determine the static and dynamic pressure in the pitot tube. The user enters the diameter of the main pipe and its length in the menu. The display of the GOLIATH then shows the speed in the main pipe and the estimated time required for gassing and the elapsed filling time, as well as the gas concentration.
