MiniSonic ISD; & PSD

minisonic isd

The Ultraflux range of MinisonicInterface , 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
