Asameters model C/G …47 _ 50 all made of stainless steel are designed for applications in potentially explosive areas thanks to their flameproof design, certified ATEX Ex ia IIC T4, T6… Zone 0 and Zone 1 (on request).
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).

- feeder for inductive switches available in safe version too
- needle valve instainless steel 316L
- differential pressure regulators in stainless steel 316L (model BL) for flows up to 20 nm³/h (air equivalent) when coupled with Asameters models C keep flow constant in presence of downstream or upstream variable pressure.
The differential pressure on regulating valve is 5 mt H2O.
They are available threaded ¼" or ½" gas-F or NPT-F.
Manufacturing materials are carbon steel (with Buna diaphragm) and s.s. 316L (with PTFE or Viton diaphragm).
Particularly suited for every kind of gas (mod. C) and liquid (mod. C/G), also with high temperature and pressure, Asameters flow-ranges are:
AIR min 0,08 nm³/h max 500 nm³/h (@ T= 20° C, @ P= 1013 mbar a)
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
