2 Introduction Purgemaster Flowmeters are low capacity variable area flowmeters for both liquid and gas with an excellent selection of material and scale lengths in a single product family design. They provide optimum flexibility with a minimum number of components. The meter features a corrosion resistant, high strength stainless steel body, quick, easy snap-in tube construction and a safety tested operar protection shield. differential pressure regular is available, which will maintain a constant flowrate of a liquid or gas even when there are pressure variations. It is supplied piped in the meter as an assembly, ready use. constant liquid or gas flowrate is achieved by creating a constant pressure drop. Manually changing the needle valve setting on the flowmeter changes the flowrate value. The differential pressure regular then maintains this constant flowrate even when the pressure varies. However when metering gases their compressibility means that although the supply pressure can change - the downstream pressure must be fixed, if the volume flowrate is be held at the set value. In addition, one or two inductive ring sensor alarms can be fitted certain model variants. These enable High, Low or even High and Low flow trip points be set and a solid state status signal transmitted. If external switching of signals is be initiated by these sensors, additional amplifiers/relays should be used. Purgemasters are ideal for applications such as the purging of control lines and instrument enclosures. Their use is easily extended in fluid sampling, liquid specific gravity, level measurement and similar services.

13 larm Unit for Purgemaster The alarm comprises a ring sensor and associated switching amplifier, available as an accessory, for glass-tube type variablearea flowmeters, type 6x/ and 6x/. lamped directly the body, the ring sensor is continuously adjustable across the overall metering range. The ring sensor can be used with all metal-float equipped flowmeters according the capacity tables. Principle of Operation The ring sensor, with a bistable switching action, energizes the relay in the amplifier when the float reaches the trigger level. It remains in that position, even if the float continues move wards the alarm zone, thus leaving the trigger level. The relay de-energizes as soon as the float crosses the trigger level from the opposite direction and moves back from the alarm zone in the normal operating range. The actual float position above or below the trigger level is indicated precisely. Operation in a hazardous area is possible, since the ring sensor used is an intrinsically safe switch with an intrinsically safe circuit. Flowmeter Model 6x/ is suitable for use either as a minimum alarm or a maximum alarm, due its short metering tube. Model 6x/ is recommended if both alarm operations are required. esign Features Sensor height mm, minimizes coverage of the scale Integrated clamp secures device directly the meter body No aumatic adjustment during operation is possible Specification Ring Sensor Part Nos. tube /8 in. type R0--N-Y6 tube / in. type R--N-Y6 Supply voltage 0 V Operating range In direction.9 m In direction.8 m Permissible resistance of control cable 00 Ω Repeatability % (T = constant) Temperature drift ±0 % Permissible ambient temperature 0 ( 0 F) Permissible process temperature 0 ( 0 F) onnection cable LIFYY x 0. mm able length m (6. ft) Housing lack Polycarbonate Protection type as per EN 609 IP67 ertificate of conformity Ring Sensor only: Flowmeter with Ring Sensor: Flowmeter without Ring Sensor: PT 99 TEX 8X II G EEx ia II T6 SEEF 0 TEX 0X II G EEx c T6 T SEEF 0 TEX 0X II G EEx c 0º Weight g (. oz.) approx.
