HM 500 Flow meter trainer
Flow measurement plays a key role in many process engineering systems. Different flow meters are used for this, depending on the medium and application.
The HM 500 trainer is used to examine different principles of operation of flow meters. The flow meters are available as accessories (HM 500.01–HM 500.16). Pressure loss curves and accuracies can be compared to determine which flow meter is suitable for which area of application.
One horizontally or vertically installed flow meter can be operated in a closed water circuit. The flow rate can be adjusted via a valve. A high-precision electromagnetic flow rate sensor is available as a reference for calibrating the flow meters.
To be able to determine the pressure losses of the various flow meters, the trainer is equipped with two twin tube manometers and a differential pressure sensor. A DC voltage source ensures the power supply to the flow meters if required.
