Production measurement (TSHD)

Reliable calculations of operational parameters

The Royal IHC production measurement (PRM) system calculates dredge pump production through electromagnetic mixture velocity and radioactive mixture density measurements. Based on over 40 years of experience, this has proven to be the best method of calculating this major operational parameter.
  • Enables verification of production figures 
  • Provides insight into pump behaviour and pipeline load
  • Short building-in length in dredge pipeline and can also be integrated
  • Several types of wear-resistant liners
  • Reliable input for several vital automation systems

Main features

  • Used for trailing, discharging and rainbowing operations.
  • Pipe diameters of 300-1300mm, with a pressure class of up to PN35.
  • Clamp-on, stand-alone or integrated measurement transmitters.
  • Fixed and replaceable liners of hardened steel, irathane and/or corundum tiles available.
  • Based on reliable physical principles for dredge mixture production measurement.
  • Very strong radioactive safety approach as verified by authorities worldwide.
  • Universal signal processing unit (MMU) with several interface possibilities.
  • Provides production outputs in tonnes of dry solids and cubic metres in situ.
  • Resettable cumulative production counter outputs for tonnes and cubic metres.
  • Trusted cross-needle yield indicator available.


Radioactive density measurement

There are over 1,300 cases demonstrating the reliability of IHC’s measurements. Radioactive sources can be reloaded for renewed use, and several sensor options can extend lifespan.

IHC can offer customers assistance with the technical, legislative, and logistical restraints that accompany the possession and application of radioactive sources through:

  • document provision
  • application filing
  • quick response to any question via
  • provision of information on EU legislation
  • end of life prewarning
  • overhaul of transmitters to any required extent.
