Grain and Feed Silo Level Measurement

Inventory control level measurement on raw feed silos allow material management automation.

The Problem
• Ultrasonic level measurement technologies do not provide the reliability or accuracy that is required for material management in grain and feed silos.
• Radar systems are unable to “see” reflections from most grains and feed stocks. Reliability and accuracy issues are common.
• RF Capacitance technologies do not provide the needed accuracy and require re-calibration with raw material variations.
• Mechanical technologies that use moving parts such as automatic plumb bobs require costly on-going maintenance.
• Manual readings do not provide the repeatability or the consistency that is required to automate material management.

The solution
• Drexelbrook DR7100 Series Guided Wave TDR level systems provide accurate level readings on all grain and feed silo level applications to 100 ft and greater.
• Reliable and Repeatable measurement accuracy within 1” of actual level with 0.04” resolution.
• Plug and Play Start-up, No calibration required.
• Easy configuration for 0% & 100% - just set it and forget it.
• No Maintenance, No moving parts, nothing to wear out, accuracy and performance unaffected by dust coatings.

Displacer switches – single, dual and tri-switch series

Single-Stage Switches

Series A10 displacer type level measurement units are wide differential units calibrated to actuate as a liquid level reaches a given displacer and to deactuate when the level reaches a second displacer. Single stage, wide differential displacer switches are factory calibrated yet field-adjustable to operate over a wide level differential band.

The minimum differential band is approximately 6 inches (152 mm) in water and varies somewhat with liquid specific gravity. The maximum differential is determined by the length of the displacer suspension cable. Series A15 units are calibrated to operate over a narrow level differential band and are ideally suited for liquid level alarm applications on either high or low level.

Dual-Stage Switches

Series B10 displacer type level measurement units are wide differential tandem switches that are factory calibrated with a choice of several switch operating sequences designed to meet virtually any application.

Series B15 units are narrow differential tandem switches that are factory calibrated. Each switch actuates at a different level.

Tri-Stage Switches

Series C10 displacer type level measurement units utilize three electrically separate control signals in a selected sequence in response to liquid level changes.

Series C15 units are wide differential switches with a choice of several operating sequences combining wide and narrow level differential and are factory calibrated.

E4 Modulevel® liquid level transmitter

The E4 Modulevel® is a loop powered, two-wire instrument, utilizing simple buoyancy principles to detect and convert liquid level changes into a stable output signal. The linkage between the level sensing element and output electronics provides a purely mechanical design and construction. The vertical in-line design of the transmitter results in low instrument weight and simplified installation. The instrument comes in a variety of configurations and pressure ratings for varied applications.

The E4 Modulevel has microprocessor based electronics with 4–20 mA/HART® digital output. E4 supports the FDT/DTM standard and a PACTware™ PC software package allows for additional configuration, diagnostics and trending capabilities.
