Install the SDM
Weld weldolet onto pipe
Install wafer or spool
Tighten bolts
Drill a hole of Ø43 mm
Horizontal pipe installation must in a 45°angle from the bottom, in
consultation with Rhosonics.
Unscrew the back lid to see the SDM’s rear view as shown on the picture above
Do not connect 220V to the SDM
Check and unpack shipment
1. Check if the box is complete and not damaged. Inside the box:
a. The Slurry Density Meter (SDM)
b. Wafer, Spool piece or Weldolet
c. Manual
Install the SDM
Follow the three installation steps shown in the picture below.
Note: Tighten the bolts following the manual guidelines, check which bolt torque values are
needed. First mount the wafer, spool or weldolet and then the SDM.
Check: Weldolet and sensor must be installed flush mounted with the surface inside the pipe.
The inner pipe diameter must be equal to the inner diameter of the wafer/spool piece.
Vertical pipe installation only if the flow goes in upstream direction. Please use the
rubber O-ring when mounting the SDM. This is important for proper sealing.
Make electrical connection
1. Connect protective earth cable (see image below)
2. Connect 24V and HART/ 4…20 mA

The set temperature must be equal to the average process temperature
IMPORTANT NOTE
The SDM is now installed, fully calibrated and ready for use!
Please always check the SDM manual for the complete details and instructions
Turn on the SDM and wait 4 hours to warm-up the electronics
Temperature setting
SDM interface: Go to Main Menu → Advanced Function→Enter access code 1802 →Go to:
Calibration menu →Temperature → change temperature with offset function
Water calibration
1. Pump clear liquid (e.g. water)
2. SDM should read value of clear liquid (e.g. water = 1.000 S.G., sea water ≈1.020 S.G.)
3. If the shown value is incorrect. Go to: Calibration menu → S.G. x 1000 → Offset →
Adjust the value of S.G. x 1000 by using the offset (e.g. 991.41 to 1.000 S.G.)
Slurry calibration
1. Pump the process slurry
2. Use a reference value to verify if the shown density value of the SDM is right.
3. If the value is incorrect. Go to: Calibration menu → S.G. x 1000 → Span → use span-
factor to change the S.G. value until it reaches the reference value. Calibration done!
