Appendix E: Application Examples; Liquid Resin In Storage Vessel, Level Measurement - Siemens Sitrans LR200 Instruction Manual

Appendix E: Application Examples

Note: In the applications illustrated below, values are for example purposes only.
You can use these examples as setup references. Enter the values in the parameter tables to
select the corresponding functions.
Configure the basic settings using the Quick Start wizard parameters. (These parameters are
inter-related, and changes take effect only after you select YES to apply changes in the last
step.)
In each example, after performing a Quick Start, navigate to the other required parameters
either via the handheld programmer, or using a Device Management tool (SIMATIC PDM or
AMS Device Manager) and enter the appropriate values.

Liquid resin in storage vessel, level measurement

Notes:
• Minimum distance from flange face to target is limited by Near Range (2.8.1.).
• We recommend using Auto False Echo Suppression with an empty or almost empty
vessel.

7ML19985JP02 SITRANS LR200 (HART) – INSTRUCTION MANUAL
To obtain level measurement/4 to 20 mA output
proportional to resin levels:
Low Calibration Pt. = 5 m (16.5 ft) from sensor
100% Level
High Calibration Pt.= 0.5 m (1.64 ft) from sensor
Max.fill/empty rate = 0.2 m/min (0.65 ft/min)
In the event of a loss of echo:
SITRANS LR200 is to go into Fail-safe High after 2
minutes.
