E+E Elektronik

Highlighting that only by knowing the exact compressed air and process gas costs will it be possible to achieve significant savings potentials, irrespective of pressure and temperature, E+E Elektronik has introduced the EE771 flow meter. The manufacturer claims that it can measure with a high degree of accuracy mass flow or volumetric flow in a supply system. The flow meter can be used effectively to measure the consumption of compressed air, nitrogen, helium, argon, oxygen or other non-corrosive gases, the manufacturer claims.

According to E+E Elektronik, the design of the flow meter is based on the direct thermal mass flow measuring principle, and adds that at its heart is an E+E hot-film sensor element proven over several million installations in the automotive industry.

It lists the following product features and advantages:

• The large 400:1 measuring range ensures precise evaluation throughout the supply system. Even the smallest volumetric flow rates are accurately recorded – an essential prerequisite whether you are calculating usage fees or finding leaks.
• The mounting concept, in combination with a ball valve, permits rapid installation and removal of the device that remains operational at all times.
• The measuring head can be exchanged in seconds without disconnecting the measuring line, which is useful for periodic recalibration.
• The integrated USB interface allows the customer to easily adapt the flow meter to specific measuring tasks.
• The two outputs available can be configured either as analogue outputs (current or voltage), switching outputs or pulse outputs for measuring consumption. The flow meter requires 18-30VAC/DC power.
