MiniSonic ISD; & PSD

minisonic isd

The Ultraflux range of Minisonic Interface, Sphere and Pig Detectors are predominantly used in the downstream oil and gas industry

Principle

The MINISONIC ISD measures the speed of sound in a liquid (or gas) product. The measured value is a precise characteristic of the product which is asssociated with its density. For both models PSD & ISD, the ultrasonic path is interrupted by the passage of a sphere (product separator) or pig even when they are travelling at high speed.

Typical Applications

Early warning of approaching interface of hydrocarbon products in a pipeline of refined or crude petroleum products : analysis of density, concentration and speed of sound.
Detection of spheres or pigs
Pipe sizes : 4'' to 60''
Programmable measurement range 500-2000 m/s
Wide range of fluids with possibility of measurement on gas (insertion probe)

MINISONIC ISD & PSD DESCRIPTION

Using advanced acoustic-signal processing, MINISONIC ISD & PSD use the signals of the associated probe to track :
The change of products in the pipeline : ISD
The passages of spheres or pigs : PSD & ISD

PERFORMANCE - SPECIFICATION

  • Resolution of the sound speed measurement
  • ISD : +/- 0,1 m/s (equivalent to < 10–4 of density)t
  • PSD : +/- 10 m/st
  • Response time < 1 s - optimized pulse sampling ratet
  • Output signals :t
  • Serial RS 232 & 485 - JBUS/MODBUS Protocolt
  • 2 relays : passage of spheres even if they are touchingt
  • 4-20 mA for speed of sound (ISD only)t
  • Keyboard and PC software for user friendly calibration – LS_ISDt
  • Storage of the 20 last records of spheres or pigs detection in a date & time logger available for interrogation by serial linkt
  • Two lines backlight LCD display : sound speed, counting of spheres and event messages
