PRODUCT
HM 500 Flow Meter Trainer
Education / GUNT Hamburg / Fluid Mechanics and Hydrology / Steady Incompressible Flow /
description

The measurement of flow rates is a key aspect of many process engineering systems. Different flow meters are used depending on the medium being transported and the application concerned. The HM 500 trainer is used to investigate the principles of operation of a wide range of flow meters. The flow meters are available as accessories. A comparison of pressure loss characteristics and accuracy of measurements establishes the suitability of the various flow meters for different applications.
 
  A pump is used to transport the water in a circuit. In the circuit there are two measuring locations at which the flow meters can be installed vertically or horizontally. A valve is used to adjust the flow rate. A high-precision electromagnetic flow rate sensor is provided for reference measurement and thus for calibration of the flow meters. The trainer is equipped with two two-tube manometers and a differential pressure sensor so that the pressure losses associated with the various flow meters can be determined.
  Some of the flow meters available as accessories require auxiliary power. A DC voltage source powers the flow meters.
