VM242A BasicMes-2

A handheld electronic measuring system for hydronic heating and cooling systems, measuring the differential pressure over an orifice, for example a valve seat.

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)
