The VA 500 is available for lines from ½'' to 40''. Thus, due to its modular design, it can be ordered with different shaft lengths, making a single sensor compatible for a wide variety of line diameters.

Conventional flowmeters, which are screwed on via flanges, can only be installed or removed in a depressurized state. Especially with large pipes, these devices are very heavy and expensive. The installation and removal is time-consuming. When they are removed, they require a precisely fitting replacement piece to be able to close the line again. Recalibration is very complicated and difficult with this kind of flowmeters.

The VA 500 only requires a ball valve via which it can be hot-tapped under pressure. The system does not have to be shut down. Due to the engraved depth scale, the VA 500 can be installed easily and accurately.

The robust stainless steel sensor tip is ideal for harsh industrial envoirements. It is protected against mechanical damage during the installation or removal. The protective bars around the thermal sensor element provide protection against dirt, particles, rust or other mechanical abrasion in compressed air lines.

With a pressure tightness of up to 50 bar, the VA 500 is perfectly suited for use in compressed air or technical gases. The electronics of the VA 500 are separated from the process by a robust glass passivation and therefore protected from water or condensate or other contaminants.

In most cases, the compressed air is not free of oil, condensate, dirt or particles. Over time, this leads to contamination of the sensor tips. As a result, measurement errors can occur, but in worst case this can also lead to total failure. Consumption meters currently on the market cannot usually be cleaned and are replaced when they become dirty.

The VA 500 can be cleaned on site quickly and without much effort by shaking it in water or a non-aggressive cleaning agent.

With the pressure-tight drilling device and a spot drilling collar, a measuring point can be set up quickly and safely under pressure. This allows a consumption measurement at any point in the compressed air network.

Unlike many conventional insertion sensors, which are fixed to the process with a safety rope or chain, the design of the VA 500 consumption sensor prevents uncontrolled ejection during installation and removal.

By means of an alignment key, the VA 500 consumption sensor can be placed easily and quickly at the correct angle to the flow. This is important to guarantee the measuring accuracy. The alignment key is supplied as standard with every VA 500.

All necessary settings during initial installation can be set on site via the keypad. These include the selection of the units, resetting the main counter, a zero point adjustment, a low flow cut off or changing the reference conditions, etc.

If the installation situation does not allow the display of the VA 520 to be seen, it can be mechanically rotated by 180° on site. Furthermore, the display can be digitally rotated via the menu keys, e.g. if the sensor is installed upside down.

In this way, the measured values can be viewed in any installation position.
