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.

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

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.

82C 82D 83D 83E87A 87B 87C 87D1/20 × Tank Height

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.

fig-3

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.

If there are agitators in the tank, the instrument should be installed as far away from these as possible. Once the installation is completed, the “”virtual echo learning” should be carried out while the agitators are running. This will eliminate the influence of false echo generated by mixing blades. If foam, strong liquid agitation or only a narrow clear volume is available then the customer should consider a guided wave radar sensor such as the Honeywell SLG-700 series.

Conduit Entry Plugs and Adaptors

Procedures
It is the User/Installer’s responsibility to install the transmitters in accordance with national and local code requirements. Conduit entry plugs and adapters shall be suitable for the environment, shall be certified for the hazardous location when required and acceptable to the authority having jurisdiction for the plant.

CONDUIT ENTRY PRECAUTIONARY NOTICE
THE CONDUIT/CABLE GLAND ENTRIES OF THIS PRODUCT ARE SUPPLIED WITH PLASTIC DUST CAPS WHICH ARE NOT TO BE USED IN SERVICE. IT IS THE USER’S RESPONSIBILITY TO REPLACE THE DUST CAPS WITH CABLE GLANDS, ADAPTORS AND/OR BLANKING PLUGS WHICH ARE SUITABLE FOR THE ENVIRONMENT INTO WHICH THIS PRODUCT WILL BE INSTALLED. THIS INCLUDES ENSURING COMPLIANCE WITH HAZARDOUS LOCATION REQUIREMENTS AND REQUIREMENTS OF OTHER GOVERNING AUTHORITIES AS APPLICABLE

fig-6

Use the following procedures for installation.
Conduit Entry Plugs

StepAction
1Remove the protective plastic cap from the threaded conduit entry.
 2To ensure the environmental ingress protection rating on tapered thread (NPT), a non-hardening thread sealant may be used.
 3Thread the appropriate size conduit plug (M20 or ½” NPT) into the conduit entry opening. Do not install conduit entry plugs in conduit entry openings if adapters or reducers will be used.
 4Tighten adapters according to the following torque: Torque: 32 Nm or 24 lb-ft

Note: Plugs do not come installed in the housings. All housings come with temporary plastic dust protectors (red or blue) installed and are not certified for use in any installation.

WIRING

Wiring must comply with local codes, regulations and ordinances. Grounding may be required to meet various approval body certification, for example CE conformity. Refer to the SmartLine Level Non-Contact Radar User’s Manual, Document #34-SL-25-13.

HART / 4-20mA Operating Ranges
The Power supply and the output current signal are carried by the same two-core cable. The allowed supply voltage range is 12V to 30Vdepending on loop resistance. There must always be between 12V and 30V on the transmitter terminals, regardless of loop current. A safety barrier (refer to Table 5 for detailed specification) should be placed between the power supply and instrument for the intrinsically safe version.
The grounding mode of current output can be adopted for the standard instrument, while the floating current output should be adopted for the intrinsically safe instrument. Normally, the grounding terminals can be connected to the grounding point of tank or an available nearby ground in case of plastic tank.

Table 5: Maximum Loop Resistance (Ω)

Supply Voltage (VDC)Max. Loop Resistance (Ω)
120
17.5250
23500
30818

A regular two conductor cable can be used as the power supply cable, and the outside diameter of the cable should be (5-9) mm to ensure the sealing of cable entry. The two ends of the shielded cable should be grounded only where allowed by the installation location. In hazardous locations, only one end of the cable can be shielded, typically on the non-hazardous side.
Remove the display to access the wiring connections

fig-8

Note: For intrinsically safe installations, shield is normally terminated at one end only
