Features gFlow 1500
Energy measurement
With current generations of EVH, the gas composition is pre-programmed into the EVH. But the gas network now consists of increasingly varying gas sources. This leads to more fluctuations in the calorific value of the gas. Even when hydrogen is blended in, significant differences will arise in the calorific value. The gFlow is part of the new generation of EVH and can be used as a flow computer with a gas quality analyzer or sensor.
In addition to correcting pressure and temperature, the calorific value and density of the gas will also be included in the correction. Essentially, we are moving from a volume measurement to an energy measurement. We use an error margin of 0.25%. This means that the measurements are very accurate. The European requirement is 0.5%.

Hydrogen is the future
Hydrogen is seen as the alternative to gas, initially for heavy industry. Many (European) countries are already working on implementing hydrogen. Hydrogen is the future, and that's why we have a hydrogen variant of the gFlow. The measuring instrument is certified for both IIB (natural gas) and IIC (hydrogen).

Features gFlow 1500
Gas quality sensor
By combining the gFlow with the GasQS floniz, a high-quality energy measurement is obtained. The gFlow corrects the pressure and temperature, and the GasQS floniz sensor records the actual measured value of the calorific value and density of the measured gas in the EVH every two minutes. This way, the actual amount of energy delivered is measured, and manual corrections are a thing of the past. gAvilar has entered into an agreement with MEMs in Switzerland, and this combination has been approved by the NMI with the aim of obtaining a MID mark.

Sturdy housing
The gFlow has a sturdy aluminum housing. The display has been specially developed for the gFlow, making the device robust yet user-friendly. The battery also has a lifespan of 5 years, and there is room for two batteries, meaning the gFlow has a battery life of 10 years.

Features gFlow 1500
Communication
In addition to the two Atex variants (gas or hydrogen), the gFlow is also available with an integrated communication module. This way, meter readings can be easily read via the 4G or 5G network. This is particularly convenient when you need multiple gFlows, allowing you to read the meter readings from your workplace. The readings can also be read physically on-site. The gFlow is easy to operate or read via a laptop with the optical reading button.
Where to find the gFlow
You can order gFlow directly from us, but we also have a network of several dealers around the world. See where to find your nearest dealer.

Gas (delivery) station VU Amsterdam
Westfalen
In the municipality of Lochem, the official opening of a unique installation took place in 2022, which provides monumental homes with hydrogen for heating.
8 bar gasnetwork in Bunschoten-Spakenburg
STEDIN
Stedin has started a trial in which the 8 bar gas network in Bunschoten-Spakenburg is used as a buffer to allow a green gas (Biomethane) feeder the opportunity to feed its produced gas into the 8 bar gas network during the night hours. The 8 bar networks Bunschoten-Spakenburg and Amersfoort are each fed by two gas receiving stations [GOS]. By closing the shut-off valves, a separation has been created between these two gas networks, with each gas network being fed by their respective GOS.
CO2 transshipment station.
Linde Gas Benelux
On May 19, 2022, a CO2 transshipment station was delivered on behalf of Linde Gas. The installation provides pure CO2 to local growers who use the CO2 in greenhouses to make the crops grow faster. The installation had to blend in with the surroundings.
Spaklerweg Amsterdam
Liandon
In 2018, gAvilar, on behalf of Liandon, built a new gas distribution station and testing facility. The installation consists of 5 lanes from 8 bar to 1 bar with a capacity of over 50,000 Nm³/h and 2 lanes from 8 bar to 100 mbar with a capacity of approximately 6,000 Nm³/h. Also housed in this space is a substantial testing installation to test gas equipment up to complete installations under gas conditions.
