GSAV-4000  is a venturi tube flow meter, specially designed to be applied to fluids sensitive to pressure loss, whose feature is a lower pressure loss compared with orifice type or nozzle type flow meter. Able to transmit the flow rate signal to the outside for checking, it can be controlled while interlocked with several peripheral devices.

It can be utilized at nearly most of industrial sites as it can be used for most of fluids (liquids, gases and saturated vapor) and also can be used at sites with high temperature and pressure. In applying to the piping it can be easily installed horizontally and vertically with a high degree of freedom having a small diameter up to a large diameter.
