Automatic Sampler Controller

• Flow-proportional control – grabs paced from meter or flow computer signals, the standard for custody transfer.
• Time-proportional control – fixed-interval grabs for steady flows or where no flow signal is available.
• Batch mode – control from batch start to batch end for tanker loading and pipeline batches.
• Single or duty and standby receivers – one receiver, or automatic receiver selection and switching.
• Safe-area cabinet – IP65 cabinet for control rooms and non-classified locations.
• Ex d or purged enclosure – for installation in hazardous areas close to the sampler.

• Receiver fills to target – the controller calculates the grab rate needed to fill the receiver over the batch.
• Proof of performance – weigh-scale or level input gives the sample performance factor for each batch.
• Early warning – alarms for low grab volume, receiver full, loop low flow and sampler fault.
• Simple integration – pulse, 4-20 mA or Modbus flow input from the meter or flow computer.
• Complete records – local touch-screen HMI with event log.
• Remote control – remote start, stop and status over Modbus RTU or TCP/IP.
• Easy support – built on an industrial PLC platform.

Power: 110 or 230 V AC, or 24 V DC | Communications: Modbus RTU and TCP/IP, hardwired I/O | Enclosure: IP65 safe-area or Ex-rated to zone | Controller: industrial PLC platform

• Designed in Canada, built in India – engineering from Vaughan, Canada and manufacturing in Chennai, India give you international design quality with competitive pricing and lead times.
• Built to your specification – we engineer to your P&ID, data sheets and company standards, and submit GA drawings and 3D models for approval before fabrication starts.
• Proven in demanding service – our high-pressure Inconel 625 sampling stations have been supplied in series to Saudi Aramco refineries, and our lab, pilot and skid systems are used by national laboratories, universities and industrial R&D teams.
• Traceable quality – PMI, dye-penetrant and hydrostatic testing as specified, EN 10204 3.1 material certificates, and NACE MR0175 / ISO 15156 materials for sour service.
• Witnessed FAT and full documentation – factory acceptance testing with you or your third-party inspector, and a complete documentation dossier with every unit.
• One point of responsibility – engineering, fabrication, testing, installation support, commissioning, operator training and spares from one supplier.
• For this product: control logic that calculates the sample performance factor for every batch from weigh-scale or level input.

Engineering to your P&ID, data sheets and company standards; drawings submitted for approval before manufacture; factory acceptance testing (FAT) with client or third-party inspection; export packing and full documentation dossier; installation support, commissioning, SAT and operator training; spares and after-sales support worldwide.
