3 Models A600 & A600 DS/A6/6EN Rev. I Introduction ABB 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. ABB 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 Models A600 & A600 DS/A6/6EN Rev. I Alarm Unit for Purgemaster The alarm comprises a ring sensor and associated switching amplifier, available as an accessory, for glass-tube type variablearea flowmeters, type A6x/4 and A6x/4. Clamped 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 A6x/4 is suitable for use either as a minimum alarm or a maximum alarm, due its short metering tube. Model A6x/4 is recommended if both alarm operations are required. Design Features Sensor height 4 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 RC0-4-N-Y64 tube /4 in. type RC-4-N-Y6 Supply voltage 0 V DC Operating range In direction.9 ma In direction 4.8 ma Permissible resistance of control cable 00 Ω Repeatability % (T = constant) Temperature drift ±0 % Permissible ambient temperature 0 C ( 04 F) Permissible process temperature 0 C ( 04 F) Connection cable LIFYY x 0.4 mm Cable length m (6. ft) Housing Black Polycarbonate Protection type as per EN 609 IP67 Certificate of conformity Ring Sensor only: Flowmeter with Ring Sensor: Flowmeter without Ring Sensor: PTB 99 ATEX 8X II G EEx ia IIC T6 BASEEFA 0 ATEX 044X II G EEx c T6 T4 BASEEFA 0 ATEX 044X II GD EEx c 0ºC Weight g (.4 oz.) approx.
