ASA C/G…47_50 Ex d asameter

Description ASA C/G…47_50 Ex d

They are suitable for medium and high flow rates with any type of gas (mod. C) or liquid (mod. C/G) also aggressive at extreme process and environmental conditions (low or high pressures and/or high temperatures).

C/G …47 _ 50 Asameters are ideal for flow measurement where safety and product reliability are a must and not require power supply (in standard version with flow indicator only) ensuring a cost-free measure even in hazardous area.

They can be supplied with flow indicator only or together with 8 digit LCD display for instantaneous, totalized and percentage flow rate with 4-20 mA output signal, Hart protocol (power supply: 24Vdc ± 10%) and Profibus PA interface (on request). All in 2-wire technology.

The installation can be vertical with upward flow (standard execution) or on horizontal pipeline (horizontal meter orientation on request).

  WATER min 2,5 l/h max 120.000 l/h
• For applications with clean air or gas at low pressures, and/or in the presence of water hammer model C is equipped with a damper.
• Available standard connections are: screwed DIN 11851; Gas-F o NPT-F; TRICLOVER; flanged PN16 UNI EN1092-1; ANSI 150..900…1500 RF/RJ; others on request.
• Max operating temperature for standard version is 150°C and 400°C for high temperature version.
• Manufacturing materials are stainless steel 316L (others on request) for metering tube, connections and all wetted parts.
• The external housing is made of die-cast aluminium, polyester painted.
• When flanged, these Asameters can have internal lining in PTFE in order to cope particularly severe working conditions (acid or alkali).
• They are available also with free float for fluids with solids in suspension.
• Available versions:
  C-G …00/47 Ex ia II C T4, T6 with microprocessor pcb
  C-G …00/50 Ex ia II C T4, T6 flow indicator only

Accessories for ASA C/G…47_50 Ex d
