Foreword
hotset's mobile D-System is a highly flexible and easy-to-use measuring device for in-situ analysis of the
energy balance of process water cycles. Wherever water circulates as a functional medium, this enables
rapid checking and visualization of flow rate, temperature progression and pressure differences. Some of
the applications of the D-System are troubleshooting, fine-tuning of fluid power processes, or monitoring
in the context of quality assurance. "Water is utilized for industrial purposes as a coolant and heating
medium, as a transport and hydraulic fluid, as an operating and drive medium, and even as a fuel
component. As a process optimization tool or mobile service tool, our D-System can therefore provide
valuable services in many industries.

Safety information
General instructions
Intended use
These operating instructions are intended to make it easier for the operator to understand and
operate the D-system.
They must be read prior to connecting the D-system, as they contain important information for
connection and operation.
The D-System includes at least one visualization and works only with one measuring module.
All electrical connections of the D-system are made by means of plug-in devices.

Connection of the measuring module
There is a number or a flow symbol at each connection of the measuring module.
It is important that the flow direction is observed, otherwise incorrect measurements or
misinterpretation of the process may occur. The supply should always be on the side that is
shown (see connection 1). Observe the connection direction as follows:
Connection 1 or the arrow points into the circle
Here, the medium must flow into the measuring module. The inlet temperature T1 and the inlet
pressure p1 are measured in the measuring module.

D-System Operating Instructions
Hotset GmbH –Hueckstraße 16 –58511 Lüdenscheid, Germany –[phone] –[email protected] –www.hotset.com –04/2021 RS 14
Connection 2 or the arrow points out of the circle
The medium comes out of the measuring module at this connection point and can be
connected from here to a measurement object, such as an injection molding tool, heat
exchanger, etc.
It is also possible to make a direct connection from port 2 to port 3. This allows, for example,
pump capacities to be determined, or temperature control units to be calibrated.
Tip: Maximum pressure and flow values of the supply (observe maximum measuring range!) can
be tested if it is possible to integrate a valve for flow regulation in the hose connection from port
2to port 3.
Connection 3 or the arrow points into the circle
If the medium has flowed through the consumer/measurement object, it is connected to port 3.
The output temperature T2, output pressure p2 and flow rate q are measured in the measuring
module.

Connection 4 or the arrow points out of the circle
The medium has now flowed through all measuring points and, if applicable, the
consumer/measurement object and is now returned to the supply via port 4.

Connection diagram measuring module
In injection molding processes, we often use the terms flow and return. However, from the
observer perspective, this definition can be understood the other way around. Here, we show
the view from the measuring module's perspective. The side with the D-SUB15 or connection
point 1+4 is the supply side, i.e. the connection point where e.g. a temperature control unit,
cooling unit or similar conveying devices are connected. At the connection points 2+3 a
measurement object, e.g. a mold circuit, heat exchanger or other test objects is connected. If,
for instance, only a temperature control unit is connected to the supply side for testing, a direct
connection (hose bridge) can be used at connection point 2+3.

Operation of the measuring module
The position should always be selected below or at the same level as the measurement object
so that any air bubbles do not accumulate in the measuring module and lead to incorrect
measurements. Make sure that the system is well vented.

Maintenance and water quality
Make sure that the medium is clean in order to avoid deposits such as lime, rust and dirt in the
measuring module. The water flowing through should be free of suspended particles and meet
the following requirements:

Using compressed air to clean or empty the measuring module can damage the measuring
components. Cleaning brushes or similar objects should also not be used to remove any
deposits. The individual components can only be cleaned carefully with a cloth once the
measuring module has been disassembled.
We recommend that you return the device to Hotset GmbH for maintenance and servicing.
