Rheonik accepts no liability for loss or damage resulting from the improper use of any of its products. Rheonik assumes no liability for the loss of production and/or consequential damage from the use of this product unless such liability has been expressly and contractually agreed. -
Page 5: Quick Start
The RHE45 is connected to the RHM ex works and cannot be removed. For mounting the RHM refer to the corresponding manual delivered with the RHM. When hot fluids are to be measured the housing of the RHE45 must not be thermally isolated from the ambient for avoiding overheating the electronics. -
Page 6: Electrical Installation
Electrical Installation Caution, the surface of the RHE45 may be hot if a hot fluid is running through the RHM sensor. Any cable used for connecting to the RHE45 must be specified for 80°C or higher. The use of shielded cable is strongly recommended. -

(see figure 5, SI1) with a rating not higher than the current carrying capacity of the cable. The ground signal of the RHE45 (Terminal 3 and 10 of the 12 pin M12 connector) is connected to PE and housing via a 10kΩ resistor. -
Page 8: Power Supply
RHE terminations to help avoid RF EMI. 3.2.3.1 Digital Outputs The RHE45 has two universal digital outputs which can be used as frequency, pulse or control/status outputs. Digital outputs are push-pull outputs compliant to IEC 60946. They can drive loads connected to ground and loads connected to +24V. -
Page 9: Analog Outputs
3.2.3.2 Analog Outputs Depending on the I/O configuration ordered, the RHE45 has passive, active or no analog outputs. The minimum current of the analog 4-20mA interfaces is limited to 3.2mA. Thus, fire state settings of 2.0mA or 0.0mA are silently corrected to 3.2mA by the RHE45 firmware. -
Page 10: Digital Inputs
The digital input 2 is available with I/O option EA and EB only. The input is located on the 8 pin M12 connector, pin 2 (DI2) and pin 3 (I/O GND). RHE45 Installation & Startup Guide – Doc. No. 8.2.1.21 – Ver. 1.00... -

Reopen the valves. Make sure that the top cover gets properly closed for achieving the IP protection. The RHE45 must not be opened in wet or dirty (dusty) ambient or when the housing of the RHE45 is wet. -
Page 13: Function Of The Pushbuttons
Function of the Pushbuttons RHE45 transmitters can be operated through three front panel pushbuttons. These are labeled “ESC” [X], “NEXT” [>], and “ENTER” []. The function of these pushbuttons depends upon the currently displayed screen. The following table details button function in specific situations. -
Page 14: Passcodes And Menu Selection
Passcodes and Menu Selection To configure and carry out certain functions in an RHE45 transmitter, it is necessary to enter a predetermined passcode. Passcodes protect configuration setup and prevent inadvertent changes to the flow meter operating condition. There are two different access levels with separate passcodes: “USER”... -
Page 15: Change Of Positive Flow Direction
Change of Positive Flow Direction Rheonik mass flow meters are bi-directional and can operate with flow passing through them in any direction. In some cases after installation, the transmitter may read negatively because of orientation. In this case, the flow direction indication can be reversed within the transmitter. To change the positive flow direction, navigate to the “Phase Measurement”... -

[R/S04] specifies the mass flow rate equivalent to the frequency set under parameter [R/S07]. E.g. when [R/S04] is set to 1kg/min and [R/S07] is set to 1000Hz a mass flow rate of 5kg/min will cause a frequency of 5000Hz RHE45 Installation & Startup Guide – Doc.
