INTRODUCTION

The Smartline SLN700L is available for both liquid and solid non-contact radar level measurement. Each model is available with a range of flange or threaded antenna, lens diameters, process connection, and accessories to suit most applications.

Mounting the Transmitter

INSTALLATION

Evaluate the site selected for the SmartLine SLN700 installation with respect to the process system design specifications in table 1. Please note that the display can become unreadable below -20C (-4°F) but it will recover once the temperature increases.

MOUNTING THE TRANSMITTER

There should be no obstacles in the area radiated by the transmitted microwave beam from the lower edge of the antenna to the material surface to be measured within the cone angle of the radar beam. These obstacles include ladders, limit switches, heating equipment, supports, etc. When these are unavoidable, the gauge offers background subtraction (“Virtual Echo Learning”) so that obstacles will be ignored during level measurement. In addition, please note that the microwave beam should not intersect with tank fluid in or out flows. In addition, the highest liquid or solid tank level should not encroach into the upper blocking distance of the gauge (typically a few cm). (see Figure 1), The instrument should be kept at a certain distance from the tank wall and the transmitting antenna should be perpendicular to the measured material surface as much as possible.

The instruments installed in a hazardous classified area shall follow the local national installation regulations.

The reference plane for measurement is the sealing surface of threads or flanges.

1.Near (blocking) distance

2.Far distance

3.Distance at which sensor reads 100% level (or current)

4.Distance at which sensor reads 0 % level (or current)

For a conical vessel with a flat tank top, the best installation position of the instrument is the top center of the vessel, which ensures that the bottom of the container is measured.

Figure 3: Conical vessel installation

Installation position

The minimum distance between the antenna and tank wall is variable for different antenna. Please refer to Table 3.to calculate the minimum distance for your particular model. In no instance, should the instrument be mounted closer than 200 mm to the tank wall.

Table 3: Minimal distance to tank wall

	SLN700 Model		Min distance to tank wall
	83A		1/5 × Tank Height
	82A 82B 83B 83C		1/10 × Tank Height
	82C 82D 83D 83E		1/20 × Tank Height
	87A 87B 87C 87D

Nozzle installations

In the case of a tank fluid or solid with good reflection properties (high dielectric constant), the sensor may be mounted on a nozzle. The background subtraction ("virtual echo learning") feature can further reduce false echoes from nozzle openings.

Table 4 shows detail of the size limitations of the nozzle.
