Bin Level Indicators.png

Operations large and small can save time and money by improving the measurement accuracy and level detection and control of powders and bulk solids in bins, silos, and hoppers. The right investment in bin level detection and control can also improve plant safety by reducing risk to workers who physically monitor bin levels under challenging conditions.

A bin level indicator (also referred to as a bin level sensor) is a device or system used to measure and monitor the level of a stored powder or bulk solid material in a bin, silo, hopper, or other container used as part of a bulk material handling process.

There are two major categories of bin level indicators available: The first offers continuous level measure and management. These indicators report bin status on a real-time basis, enabling just-in-time replenishment. The second offers point level control. This bin level indicator category provides simple alerts to prevent bin overfill or empty conditions.

We represent the industry leaders in bin level detection, level measurement, and level monitoring. We offer the most comprehensive line of quality bin level indicators available anywhere. In addition, our inhouse expertise in bulk solids-handling products and services allows us to provide you with the comprehensive advice you need to choose the right approach to optimizing your operation.

Types of Bin Level Indicators & Flow Detectors

Point Level Indicators

Point Level Indicators send an alert when the material reaches a particular level, helping to prevent bin overflow. Includes rotary paddles, capacitance probes, diaphragm switches, tilt level sensors, vibrating rods, and all related accessories.

Continuous Level Sensors

Continuous bin level inventory management equipment will report bin status on a real-time basis, enabling just-in-time replenishment and optimal efficiency for operators. Technologies available include ultrasonic and radar bin level sensors, non-contact 3D scanners, cable-based bobs, and lasers. Applications include baking and snack ingredients, biofuels, cement and aggregates, chemicals, coal, wood products, fly ash, pharmaceuticals, plastics, pulp and paper, and salt and minerals.

Plugged Chute Detectors

Plugged chute detectors alert operators when the flow of a bulk solids chute is obstructed, using audio and visual signals. This alert lets you address the issue in a timely manner, and can be used in tandem with flow aid devices to keep your facility running efficiently.

Bulk Solids Flow Detectors

Flow sensors and detectors alert users if the flow status of solids or powders changes, power is lost, or communication is interrupted. Systems consist of a remote sensor probe mounted in either a gravity chute, or feeder, and a control console mounted in an area accessible to users.
