Product Overview

Purpose-built measurement, clearly presented.

The CONG Prima-10 is a two-component online analyzer system comprising an explosion-protected Dew Point Transducer and a Central Control Unit installed in a safe area. One chilled-mirror measurement cell can register water dew point, hydrocarbon condensation temperature, or both values alternately.

The system is available with a gas-preparation arrangement or a direct-pipeline module. Blue Dragon Technology reviews the measurement ranges and accuracy, line and measurement pressure, gas composition, contamination risks, supplemental cooling, sample-system architecture, installation areas, Central Control Unit location, input and output requirements, and commissioning method before configuration.

Distinctive Capabilities

  • Laboratory-quality chilled-mirror measurement in an online field system
  • Water and hydrocarbon condensation measurement with one transducer cell
  • Central Control Unit for operation, diagnostics, and plant data interfaces
  • Sample-system and direct-pipeline installation configurations
  • Smart mirror-cleaning function with no routine analytical consumables
Performance & Technical Data

The measurement method and the values that matter.

How it measures

Measurement Principle

The Dew Point Transducer cools a mirror while a laser-based interferometric optical system monitors the surface for condensation. The mirror temperature at the detected onset of water or hydrocarbon condensation is registered by the transducer. The Central Control Unit provides operational control, diagnostics, adjustment, and digital and analogue plant interfaces.

Application Engineering Notes

Range and cooling selection

Water and hydrocarbon measurement ranges are selected configurations rather than one continuous combined range. Supplemental cooling is required for water dew-point measurements below -30 °C.

Ordered configuration

The approved order identifies the selected ranges, required water-dew-point accuracy, measurement pressure, pressure and temperature inputs, sample-system or direct-pipeline arrangement, and Central Control Unit power supply.

Project Integration & Support Scope

Blue Dragon reviews the measurement objective, interfaces, documentation, commissioning, and lifecycle requirements as part of project configuration. The scope below identifies the principal items to confirm before order placement.

Measurement Objective
Automatic online measurement of water dew point, hydrocarbon condensation temperature, or both alternately in natural gas, with safe-area operation and plant-data interfaces through the Central Control Unit.
Signal Outputs
The Central Control Unit provides RS-485 Modbus RTU, RS-232 Modbus RTU, and two 4-20 mA outputs. It can accept 4-20 mA pressure and temperature inputs. Final scaling, register mapping, correction logic, and alarm use are project specific.
Data Integration
Integrate the Central Control Unit with the DCS, PLC, SCADA, historian, or metering system. Define reported parameters, measurement mode, engineering units, pressure basis, pressure and temperature inputs, quality flags, and ownership of corrected values.
Alarms & Diagnostics
The project should define analyzer status and diagnostic handling, high water-dew-point and hydrocarbon-condensation alarms, sample-system alarms, cooling status, communication failure behavior, and local or control-room indication.
Documentation
The project package may include the manufacturer product sheet and operating manual, approved datasheet, metrological and hazardous-area certificates, dimensional and wiring information, communication details, sample-system drawings, and FAT or SAT records as ordered.
Commissioning Support
Commissioning can include mechanical and electrical inspection, pressure and leak testing, flow setup, cooling checks, mirror and sample-path inspection, Central Control Unit setup, analogue and Modbus tests, alarm simulation, and reference comparison.
Lifecycle Support
Lifecycle support covers mirror and sample-system maintenance, filters, seals, pressure and temperature inputs, cooling equipment, communications, verification, spare parts, metrological service coordination, troubleshooting, and technical assistance through Blue Dragon Technology.
Online Analyzer Configuration

Sample System & Online Analyzer Readiness

Installation Area
Confirm hazardous-area classification and location for the transducer, safe-area location for the Central Control Unit, ambient exposure, shelter or panel space, cable route, direct-pipeline mechanical requirements, and maintenance access.
Utilities
Confirm the Central Control Unit and accessory power supplies, approved hazardous-area wiring, grounding, sample flow, supplemental-cooling utilities, heating, ventilation, drainage, and safe vent or return.
Response Requirement
State required cycles per hour, sample transport distance, acceptable stabilization time, alarm delay, and response expectations following process changes, range changes, or alternating water and hydrocarbon measurement.
Integration Requirement
Define RS-485 and RS-232 Modbus use, two 4-20 mA output assignments, pressure and temperature input scaling, correction logic, alarm mapping, quality flags, historian tags, and operator display requirements.
Commissioning Requirement
Confirm mechanical and electrical checks, pressure and leak tests, flow setup, cooling test, pressure and temperature input checks, output and Modbus tests, alarm simulation, reference comparison, training, and records.
