Pressure, pressure impact and flow rate measuring instrument


FLOWMAT is a self-contained mobile instrument that measures pressure, pressure impact and flow rate. The fluidic and electronic parts are packaged inside the case system. The fluidic part contains a flow rate meter with a range of 0 to 60 m3/hour. With an output signal of 2-litre impulses, even small flow rates are easy to measure. The pressure sensor fitted to the same measuring circuit covers a range of 0 to 25 bars and also allows pressure impact to be registered thanks to permanent measurement!

The electronic part is a data logger that processes and saves the output signals of the measuring units (flow rate/pressure) for further digital processing through a PC interface.

When taking measurements in the field, all the data can be displayed on-line via a connecting cable and a PC. The complete power supply is located inside the data logger in the shape of a special lithium cell with a correspondingly long life (approximately 6 months operating time).

A FLOWMAT pressure and flow rate measuring instrument can record pressure impact, long-term pressure measurements, flow rate measurements and can determine Q max, e.g. for hydrants or general flow rate measurements when locating leaks.

The system is compact, light and designed for heavy-duty use in the field.
