EESIFLO 8000 Series Explosionproof Ultrasonic Flow Meter


The EESIFLO Sonalok X 80 and 81 are products from the 8000 series generation of flow meters certified to ATEX Zone 1 and 2, suitable for installation on all types of sonically conductive pipes containing water, chemicals or hydrocarbons. The advantages are elimination of pressure loss, no downtime during installation coupled with high accuracy and repeatability in flow measurement. One of the most common applications for the flow meter is process flow measurement and balancing/checks in areas where it is either impossible or uneconomical to install a conventional type hazardous area flow meter. The meter can be set up within minutes using a magnetic pen and it comes with an optional second channel.
