Monitor’s line of BINATROL® diaphragm
bin monitors consists of economical, reliable, and durable
point level controls for point level detection of dry bulk
materials. The units can be used to eliminate bin overflow,
maintain a predetermined material level, indicate plugging
of chutes or conveyors or provide any of a number of level
control functions. The flush mount, non-intrusive BINATROL
units are ideally used when vessel size or internal clearance
is limited, or where protrusion into a vessel is not acceptable.
All installation and servicing, including diaphragm replacement
and sensitivity adjustment, can be done from outside the vessel.
bin monitor provides level indication by detecting pressure
applied by the bulk material to the sensing diaphragm. The
unit is installed to a vessel wall so that the diaphragm
is exposed to the material to be sensed. As material contacts
the diaphragm, a force is exerted through the diaphragm to
a pressure plate within the bin monitor. Physical deflection
of the pressure plate activates an internal switch which
is user accessible for signaling alarms, lights or PLC inputs.
When material recedes from the diaphragm, a light duty spring
returns the pressure plate and internal switch back to their
The BINATROL® diaphragm pressure switches / bin monitors
can be used to detect high, low and intermediate product levels
on dry material storage bins. The BINATROL can be used on either
flat or curved surfaces. For bins with a diameter greater than
12' (3.6m), extra gaskets are not required. For certain applications,
the BINATROL can also be used to detect plugged or backed-up
conveyor chutes. Depending on the selected options and accessories,
these units can be used with light powders, granules, materials
with varying particle sizes, pellets, and abrasive and corrosive
materials. These products are not normally used with materials
which are very light, sticky or of large particle size.
Typical Applications include, but
are not limited to:
The simple design of BINATROL® diaphragm pressure switch
/ bin monitor provides for maximum ease of use. The BINATROL
operates using a "floating" diaphragm,
which is free of the electric switch mechanism. Diaphragm movement
as little as 1/32" (0.8mm) triggers the unit. Also, the
BINATROL pressure switch has no driven parts and thus requires
no auxiliary power source.
These design features ensure reliable and durable, low maintenance
The BINATROL® offers a sensitivity adjustment that
is accessible from outside of the bin and easily adjusted
with a screwdriver. This enables the user to adjust the
sensitivity of the unit, should vessel contents change,
without removing the unit from the vessel.
The low profile mounting of the BINATROL® unit eliminates
major protrusions into the bin. This minimizes obstruction
of the material flow in the vessel or chute. Also, the beveled-edge
construction eliminates any possibility of material lodging.
The BINATROL® diaphragm din monitor incorporates a
unique sensing plate which provides for overpressure protection.
This feature prevents damage to the unit due to heavy loads
or forces. In the event that a heavy load is applied to
the sensing plate, a mechanical stop prohibits the plate
from exerting excessive pressure on the sensitivity spring.
INSTALLATION / MAINTENANCE
One of the biggest assets of the BINATROL® diaphragm
bin monitor is the ability to install and maintain the
unit from outside of the vessel. All parts, including the
diaphragm are accessible from outside of the bin, without
removing the mounting flange. This enables the user to
install the unit, change diaphragms and perform basic maintenance
without removing the entire unit. For applications which
require installation from within the bin, this can also
be easily accomplished.
The Model G is the most basic BINATROL® diaphragm bin
monitor. It provides accurate point level control on most
bin types for products ranging from pellets to fine powders.
The Model GX offers all the features of the Model G, but is
specially designed to provide dust-ignition proof protection.
This model should be used in applications which require Class
II dust-ignition proof approval.
The Model GX-SS is the dust-ignition proof version of the Model
G with a type 321 stainless steel diaphragm. This diaphragm
provides corrosion resistance when used with corrosive materials
or added protection in abrasive applications.
The Model G and GX BINATROL® units are available with
two different diaphragm materials.
Diaphragm: The standard diaphragm is constructed of neoprene
and is compatible with most basic applications.
Teflon® Diaphragm: A Teflon® diaphragm
is available for use in high-temp applications. This diaphragm
can also be effectively used in sticky applications.
The Model G, GX and GX-SS units come with a standard SPDT switch.
However, for applications involving lightweight materials,
Models G and GX can be specified with an ultra-sensitive switch.
Monitor offers a HYCAR® (oil resistant) cover for the
diaphragm for watertight applications and to provide additional
abrasion resistance. This cover is typically used with
Models G and GX.

Mass Flow Measurement Systems
The QuantiMass in-line mass flow sensor measures the flow of quantities in pneumatic conveying & free-falling processes. The sensor is based on the latest Microwave Doppler Effect technology and provides fast, in-line / on-line measuring without the use of weight scales.
The sturdy, non-intrusive design of the sensor minimizes maintenance. In addition, the compact size of the sensor makes for easy installation into existing processes. Suitable for powders, dust, pellets, and granular up to 0.75 inch (2cm).
Ultra Series-Includes controller
PRO Series-Includes transmitter
A practical application for the QuantiMass would be to monitor material flow rates to verify blending mixture ratios.
Principle of Operation:
The QuantiMass Mass Flow Measurement Sensor / Meter is designed with the latest microwave technology and is used to continuously quantify the flow of powders & solids being conveyed in metallic pipes. The QuantiMass is based on technology that has been developed and proven by Muetec Intruments over several years. The measurement process of the sensor is centered on the Doppler effect. The mass flow-rate is determined by evaluating the frequency and amplitude changes during the measurement process. Particles at rest, such as deposits, do not influence the measurement. All powders, dust, pellets and granules can be measured reproducibly, up to the size of 0.75 inch (2cm). The QuantiMass sensor is suitable for continuous in-line / on-line measurements in pneumatic conveying or in free-fall pipelines.
