Page 4: Device Description
DM04 Device description The devices of the DM04 series from PKP, is a non-contact flow sensor. The measurement is performed us- ing magnetic induction and works without any moving parts. The DM04 is used for measuring or metering water and aqueous solutions. The compact design and inde- pendence from the intake and discharge sections allows the DM04 to be used under a variety of conditions. -
Page 5: Intended Use
Measuring tube empty (or partially filled). / Conductivity too low. The green LED may blink irregularly if the measuring tube of the DM04 is empty or partially filled or if the conductivity of the fluid being used is too low. Random pulses will be present at the output, but they do not represent an actual flow. -
Page 6: Safety Instructions
Prevent freezing of the medium in the device with appropriate measures. Only use the DM04 if it is in perfect condition. Damaged or faulty devices must be checked without delay and, if necessary, replaced. When fitting, connecting and removing the DM04 use only suitable appropriate tools. -
Page 7: Construction And Function
The two stainless steel electrodes are located in the middle of the measuring tube between the earthing sleeves. The DM04 does not need any moving parts to make measurements. The inside of the measuring tube is completely open, allowing the fluid to flow unhindered through the measuring tube. -
Page 8: Installation Of Dm04
Ensure that no external magnetic fields are present at the installation site of the DM04. The DM04 can always be installed anywhere along the pipeline. Straight sections of piping are prefer- able, however. - 7 - PKP Prozessmesstechnik • 08/2019... -
Page 9: Mounting
The inlet and outlet sections and the gaskets must have the same or a slightly larger inside diameter than the measuring tube in order to achieve the specified accuracy. 4.2 Mounting The DM04 is installed directly into the pipeline. The compact design and light weight of the unit make wall- mounting unnecessary. IMPORTANT NOTICES: ... -
Page 10: Electrical Connection
DM04 Electrical connection The electrical connection of the DM04 is via the 5-pin plug M12x1 at the top of the housing. The wiring of the DM04 depends on the ordered version. A distinction is made between frequency and ana- logue output, as well as basic and optional wiring. -

the measuring system is vented by flushing. 6.2 Switching on and off The DM04 has no switch and can therefore not be switched on and off independently. Switching on and off takes place via the connected supply voltage. Switch on the supply voltage. - Page 13 Instruction Manual DM04 DM04 with analogue output: According to the configuration of the DM04, the analogue output provides a voltage or current sig- nal. This signal is proportional to the measured flow. - 12 - PKP Prozessmesstechnik • 08/2019...

Page 14: Maintenance And Cleaning
DM04 Maintenance and cleaning Maintenance: The DM04 is maintenance-free and cannot be repaired by the user. In case of a defect, the device must be re- placed or sent back the manufacturer for repair. CAUTION! Material damage! When opening the device, critical parts or components can be damage. -
Page 15: Disassembly And Disposal
Disposal: NO HOUSEHOLD WASTE! The DM04 consists of various different materials. It must not be disposed of with household waste. Take the DM04 to your local recycling plant send the DM04 back to your supplier or to PKP. -
