Product Description
SF-500S | LXD-04

II . PRODUCT
SF-500S is an ultrasonic non-contacting flow meter for open channels. The
measured level value is converted into the rate of flow in specific weirs or
flumes therefore the accurate level value is very important. LXD-04 is an
exclusive sensor for open channel flow, it provides accurate level reading.
SF-500S provides a variety of weirs and flumes formulations so it can be used
in different applications. The measured flow information is saved in the
memory of SF-500S and it can be downloaded by USB or transmitted by the
digital communication such as RS232, RS485 or Modbus.
Application:
LXD-Series sensors are suitable for liquids level monitoring in all industries,
particularly in the water and wastewater industry.
Weirs & Flumes
 Parshall Flume
 Suppressed Rectangular Weir
 Contracted Rectangular Weir
 V-Notch[Triangular]Weir
 Cipolletti Weir
 Leopold Lagco Flume
 Palmer Bowlus Flume
 H Flume
 Trapezoidal Flume
•Compatible sensor is only LXD-04.
•XDS-300 sensor is not compatible with the SF-500S controller.
•Depending on the sensor material, the application can be restricted.
Before installing the sensor, please check the chemical compatibility
chart.

1. Principle of operation
LXD Sensor transmits ultrasonic pulses to the measurement target. The
pulses are reflected from the surface of the target and received back by the
sensor. The running time is converted into the distance and it is converted
the level. The measured level is also converted into flow rate according to the
selected primary measurement device of SF-500S.

III. Installation
1. General Guide
Before mounting the product, read this manual and specification. It is
installed in a place that is within the temperature range specified in this
manual and that is suitable to the enclosure rating and materials. If the
products are installed improperly, it may cause malfunction.
This is general guide for installing SONDAR products.
Remove the obstacles in the space between the sensor and the measured target
such as ladders, limit switches, heating spirals etc.
When mounting the sensor, keep the distance to the vessel wall.
The bottom of the sensor should be perpendicular to the surface of water.
Do not set the maximum level into the Dead Zone range.
Avoid the intense winds and excessive exposure to direct sunlight. The strong
winds change the path of ultrasound and may cause a malfunction. If you need
to install the unit in a spot exposed to direct sunlight, sun screen must be
installed.
Keep the distance from the place where are strong noise by high voltage, high
current etc.
Install the unit in the place vibration free.
