6. Installation
6.1 Transceiver Installation
6.1.1 Wall Mounting
1. Attach the mounting bracket to the wall and mark the two holes(around 16mm) on the wall.
Note: The connecting line of two holes must be a horizontal line.
2. Drill the holes according to the marks and screw the mounting screws into the wall.
3. Mount the device on the wall.
6.1.2 Pole Mounting
1.Loosen the hose clamp by turning the locking mechanism counter-clockwise.
1. Straighten out the hose clamp and slide it through the rectangular holes in the mounting
bracket, wrap the hose clamp around the pole.
2. Use a screwdriver to tighten the locking mechanism by turning it clockwise.

EM500-SWL User Guide

6.1.3 DIN Rail Mounting
Use 2 pieces of M3 × 6 flat head Phillips screws to fix the DIN rail to the device, and then hang
the DIN rail on the mounting bracket. It is necessary to choose a standard bracket.
6.2 Sensor Installation
Lower the sensor via cable into the media until it is close to the bottom of tanks or ponds. Be
careful not to hit the bottom hard or touch hard objects like sand or sludge since it will damage
the sensor.
Note:
Ensure the gas holes of transmitter do not be blocked while mounting or using it.
To prevent the separation of level sensor and transceiver due to water shock and gravity,
please fix the sensor cable with a fixed bracket or wrap it around the pole.
If the sensor is to be used in a well or other locations with turbulence or other disturbances, it is
advisable to install a pipe to protect the sensor. Several holes should be drilled at different
heights of the pipe in order to let water flow into and remove dydrodynamic pressure.
Note: The pipe can’t be placed bend.
