Braukmann VM242A BasicMes-2 Handheld Flow Measurement Computer

Braukmann VM242A BasicMes-2 Handheld Flow Measurement Computer

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

Product Description

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)
