Rion VM-230A/240A Acoustical Capacity Tester

Rapid and dry method for measuring engine cylinder capacity.

FEATURES & BENEFITS

  • Uses sound to measure the volume of irregularly shaped spaces
  • Designed specially to measure engine cylinder capacity
  • Once the system is set up it takes around 2 seconds to measure cylinder capacity
  • VM-240A is placed on the cylinder head during engine manufacture or maintenance
  • VM-230A can be used to measure cylinder capacities on a fully assembled engine via spark plug sockets
  • Used by engine and vehicle manufacturers around the world

PRINCIPAL APPLICATIONS

  • Automotive Sound & Vibration
  • Engine Manufacturing
  • Engine Testing

Product Description

The Acoustical Capacity Meter was primarily developed to measure the capacity of engine combustion chambers either on the head assembly itself (using the VM-240A) or on a complete engine via the spark-plug fitting (VM-230A).

These measurements allow the engineer to quickly determine that the compression ratio of each cylinder is correct in far less time than it would normally take, using the traditional oil-filling, burette method.

The Acoustical Capacity Meter enables the rapid and accurate viscosity and volume measurement of irregular shapes without the use of liquids therefore has a broad range of potential additional applications.
