It is important to know the discharge depth for many experiments in open channel flow.
Using HM 162.13, the discharge depths in form of pressure heads are recorded. For this purpose, the measuring amplifier is connected to the switch cabinet of HM 162 or HM 163 and automatically identified by the PLC. Depending on the experiment, up to ten selected measuring points can be connected along the experimental section of HM 162 or HM 163.
The measured values are transmitted to a PC via a CAN bus connection. By matching the pressure sensors with the measuring points, a curve of the pressure heads along the experimental section can be displayed in the software. The recording of the flow rate enables the display of the pressure head as a function of the flow rate.
A second measuring amplifier HM 162.13 can be used simultaneously to display the pressure heads of 20 measuring points of the experimental section.
