The DK10 process flap flowmeter is available in a large selection of wetted construction materials, including aluminum, bronze, cast iron, stainless steel, polytetrafluoroethylene (PTFE) and polyvinyl chloride (PVC). Its shafts can be made of titanium, Hastelloy or plastic for processing aggressive liquids. The flowmeter is available with a choice of one or two alarm level outputs, as well as an analog 4–20-mA output. The flow in the line causes a spring-loaded flap mounted inside the unit’s hemispherical chamber to deflect by an amount that is directly proportional to the flowrate. This movement is transmitted, via a shaft that is isolated from the process, to a mechanical pointer, and the flowrate is displayed on a scale. Each flowmeter is calibrated for the specific liquid being monitored based on customer specifications. The units are available with G or NPT threads for 0.25–2.0-in. pipes and as a wafer for mounting between two DIN or ANSI flanges on DN80 (3 in.) to DN200 (8 in.) pipes,
