Handheld flow measurement computer

Product specification sheet


The VM242A BasicMes-2 consists of:

  • Handheld flow measuring computer with colour display, rechargeable batteries and lanyard
  • Bypass assembly for zero calibration and venting of the hoses
  • Red and blue pressure hose
  • Adapters and accessories
  • Carry case
  • For a detailed parts list see ‘Scope of Delivery’ further below


The BasicMes-2 is a handheld measuring computer for flow measurements in hydronic heating and cooling systems.

The BasicMes-2 measures the differential pressure over an orifice, for example a valve seat. Together with the kv-value of the orifice the flow is calculated using the kv formula. The kv-value of all Honeywell balancing valves as well as some common valves of other manufacturers are stored in an internal database. Manual input of the kv-value is also possible.

Apart from differential pressure and flow measurement the BasicMes-2 has the following functions:

  • Two temperature sensor inputs for simultaneous (using two sensors) or successive (using one sensor) temperature measurements
  • Data logging function with programmable interval and duration
  • Leakage test with programmable test pressure and duration
  • Memory to save measured values
  • PC connectivity to download measured data from the device onto a PC including PC user software
  • Print function in combination with optional pocket printer (accessory)

Special Features

  • Easy to use device with compact dimensions
  • Large backlit colour display
  • Integrated valve database
  • Bypass for venting of hoses and zero calibration
  • PC connectivity with software included
  • Robust case for device, accessories and optional pocket printer
  • Magnet on back to attach to metal surfaces
