High Pressure Casing Underwater Measurement

The High Pressure Casing of PetersInvent i.c.w. the Infrared Reflection System is suitable for flammable/explosive liquids. Due to the absence of electricity in this design it is safe to use this flow meter with hazardous flammable liquids.
Second advantage of this system is the ability to dip the complete sensor itself in the fluid even at a considerably depth.

The reflection system is made of a thin 3mm tube which makes it possible to shrink the size of the pressure casing w.r.t. the infrared system. This model comes with a 1⁄2” external thread in order to keep the flow as big as possible.
