NRG GLOBAL MAKE all plastic fittings to eliminate corrosion completely. The meters are useful for measuring flow of air, common gases, water and many organic chemicals, excluding petrolelum products. Applications include purging of gas lines, anaesthesia, laboratory instruments, leak detection, cable pressurization, industrial furnaces and chromatography etcThe essential working part is a tapered flow tube precision machined inside the acrylic body. When flow occurs, the position of a float within the tube indicates flowrate on a calibrated scale engraved on the acrylic body. With integral construction, a needle valve and flow parts (Model FSA & FSB) are built into the acrylic body, resulting in a very compact and ecnomical design. The unique "front plate" design (Model FSB) the beauty of any panel where the meter is installed.
