Level indicators
LI401 Level Controller
The LI401 Digital Indicator, is a microcontroller based instrument providing continuous measurement of material levels within silos and storage vessels for both new and existing applications. The instrument’s user interface and indication of material level is displayed via a graphical LCD. The LI401 provides an isolated 4-20mA current loop to directly indicate the level of product
inside a vessel, two programmable setpoints with mechanical relays to control external devices and a dedicated system healthy relay. The LI401 is designed with optional fieldbus communication plug-in card for protocols such as Ethernet-IP, Modbus-TCP, DeviceNet and Profibus.
Standard Features:
- Auto Zero
- Adjustable digital filtering
- Programmable access code
- Diagnostics menu
- Data logging to SD card
- USB port for data downloads
- Compact flashcard reader for calibration data storage
- System “Healthy” output

- Optional 304 or 316 Stainless Steel Enclosure
This controller has been designed designed to simplify the process of setting up bin level and silo weighing systems by removing the requirement of add-ons.
Combined with the large range of Rice Lake Weighing Systems indicators, we have the weighing solution for most applications.
Our current range of level controllers/integrators include
Electronics Controller Options
- Stainless steel enclosure
Stainless steel enclosures are available for applications in harsh environments. Enclosures can be either 304 or 316 grade stainless steel and can either have a flat or 30°sloped roof.
- Intrinsically safe
“Intrinsically Safe Enclosures” are available for all Electronic controllers
- SunshadeGenerally all electronics are temperature limited.
Electronic instrumentation field mounted in IP66/Nema 4 rated enclosures prevent heat loss by means of air convection. Enclosures manufactured from modern plastics, fiberglass and stainless steel also prevent heat loss by means of conduction. It is therefore important to restrict any additional heat input such as from the sun. Web Tech AutoWeigh has designed a sunshade that accommodates the entire range of electronic integrators or indicators in HDPE or stainless steel with a 30° sloping roof. The sunshade does not provide any protection from water or dust for the indicator which is still mounted in an IP66/Nema 4 enclosure. It does, however effectively shade the indicator and enclosure from radiant heat. Air circulates through and around the sunshade.
Conduit entry to the instrument enclosure is made easy owing to the generous opening at the base of the sunshade.The design allows for retrofitting of the sunshade without the need to disconnect the indicator wiring/conduits. - Optional Stainless Steel Sunshade
- Optional beacon
- Available Post mounted
