Agar ID-200H Specifications and Installation Planning

This engineering summary is based on the published Agar Corporation ID-200H Series brochure. Confirm the final model, materials, connection, certification and operating limits with PMA before specifying or installing an instrument.

Models and output

  • ID-201H: 1/2 inch shaft
  • ID-202H: 1 1/4 inch shaft
  • Power and signal: two-wire, 4-20 mA loop powered
  • Communication: integrated HART
  • Measurement: liquid-liquid and vapour-liquid interfaces, including emulsions and foam

Published operating range

  • Emulsion concentration: 0-100% hydrocarbon/water by volume
  • Standard process temperature: 0°C to 149°C (32°F to 300°F)
  • High-temperature option: 0°C to 232°C (32°F to 450°F)
  • Ambient temperature: -40°C to 85°C (-40°F to 185°F)
  • Pressure rating: up to 3000 psi, configuration dependent

Materials and process connections

Standard probe construction: 316 stainless steel, Teflon and PEEK. Published optional probe materials include duplex, Hastelloy and Monel. Standard seals are Aflas and Teflon, with Viton listed as an option. The brochure states NACE compliance.

Published connection options include 2 inch NPT seal housings in 316 stainless steel or carbon steel; 3/4 inch NPT compression fittings in 316 stainless steel or carbon steel; and ANSI 150 to 1500 class flanged connections.

Installation planning checklist

  • Confirm normal, start-up and upset temperature and pressure.
  • Check wetted-material and seal compatibility with every expected phase and cleaning chemical.
  • Select a probe position that sees the representative interface and remains serviceable.
  • Define loop power, 4-20 mA scaling, HART access, alarms and control-system integration.
  • Review valve fail position, interlocks and the response to invalid or lost measurement.
  • Plan commissioning against samples or other process evidence and document the accepted thresholds.
