The gFlow accurately measures how much gas you have consumed. Without EVC, consumption is often an estimate. The gFlow then converts the volume of the gas under operating conditions to volume under standard conditions, correcting for pressure and temperature differences. The metering company receives this data for processing. This is very accurate, so there can be no dispute about whether you are paying too much or too little.

The gFlow is a device that connects to the gas meter. If you consume more than 175,000 m³ of gas per year, you are legally required to use an EVH. It may also be interesting to use an EVH for lower annual consumption. With rising energy prices, you are always billed correctly instead of estimates based on the ground temperature method. Everyone benefits from accurate measurement. This way, lawsuits and claims are avoided.
The innovative MEMS GasQS™ flonic sensor ensures seamless integration with the gFlow1500, offering unparalleled precision in measuring gas volumes and qualities. This makes it possible to determine not only the quantity but also the calorific value of the gas with utmost precision, which is crucial for an accurate energy measurement. In addition to the calorific value, the relative density and compressibility of the gas are also measured. These values are then used by the gFlow1500 for correction.
gAvilar specializes in designing, building, and installing gas-related pressure control and metering stations. With our Bio2Grid, we are active in the green gas sector and also supply CO2 measurement, control, and reduction installations. We are also actively involved in the first pilots in the field of hydrogen distribution and odorization systems. One of our core activities is the development, production, and sale of control equipment.
gAvilar is a leading manufacturer of Electronic Volume Conversion Instruments (EVE) and communication equipment, gas pressure regulators, safety fittings. We also provide extensive services in the maintenance of (natural) gas equipment and systems, and Scios inspections 7a and 7b.
Stedin
In the municipality of Lochem, the official opening of a unique installation took place in 2022, which provides monumental homes with hydrogen for heating.
Westfalen
Stedin has begun a test run to use the 8 bar gas network in Bunschoten-Spakenburg as a buffer in order to enable a green gas (Biomethane) feeder to feed the gas it produces into the 8 bar gas network during the night. The 8 bar networks in Bunschoten-Spakenburg and Amersfoort are both fed by two gas receiving stations [GOS]. By shutting off valves, these two gas networks are separated, which allows each gas network to be fed by their respective gas receiving station.
Linde Gas
On May 19, 2022, the delivery of a CO2 transfer station was commissioned by Linde Gas. The installation supplies pure CO2 to growers in the area who use the CO2 in the greenhouses to make the crops grow faster. The installation had to blend into the environment.

All makes and brands which offer a low frequency, high frequency or encoder output. Please contact us if you’re in doubt.
With the optional communication board you can connect the gFlow via 4G/LTE.
To use the configuration program you will need either an RS485 connection or an optical connection via the optional IR head. To connect to the gFlow remotely you can use the optional 4G/LTE communication board.
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%.
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.
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).
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.
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.
