The KOBOLD KSV Series Flowmeter is a low volume measuring and controlling device calibrated for flows of water or air. The unit has a plastic body with metal fittings and is kept leak tight through the use of O-ring seals. The floats are either aluminum, stainless steel, glass, or titanium. Though the float types are determined by measuring range, the customer has a choice of plastics for the body and metals for the fittings. The KSV is supplied with or without a needle valve, depending upon the order number.

Four material combinations are available: Combination I (polycarbonate body, brass fittings, Buna-N O-rings, 130°F), Combination II (polycarbonate body, 303SS fittings, Viton O-rings, 130°F), Combination III (polysulfone body, brass fittings, Buna-N O-rings, 250°F), and Combination IV (polysulfone body, 303SS fittings, Viton O-rings, 250°F). The polysulfone version has excellent resistance to acids & alkaline solutions and can be sterilized up to 250°F.

Accuracy is ±6% Full Scale with ±1% Full Scale repeatability. The KSV is easy to read and to install, with convenient panel mountability. It is recommended that the needle valve version be used to help stabilize the float during introduction of media (particularly gases) into the flowmeter. Complete shutoff cannot be achieved with the needle valve; if desired, a separate shutoff valve upstream is recommended.
