TRANSCRIPT
Effectively Measures Level with a Unique, Patented Method
Patented principle of level measurement
More than 3500 tanks/silos currently using —since 1992
Designed for “difficult” applications
2
Tank heights up to 130’(and taller!)
Dielectric constants as low as 1.6(and lower!)
Up to 24 tanks per control unit(and more!)
3
Available in many semi-custom configurations for temperature and pressure
Intrinsically safe, CSA, CENELAC versions are available
4
A system has:
A Control Unit that can monitor up to 24 sensors
One or more Sensors of a variety of lengths and designs
Optional Inventory Software
5
How it works:
A change in impedance echoes the transmitted signal
The phase difference between transmitted and echoed signals determines level
Transmitsignal
Reflectedsignal is outof phase withtransmit
6
Different than MIR (radar):
Much lower frequency, less affected by noise
Does not use timing to determine length, less error and longer lengths
Transmitsignal
Reflectedsignal is outof phase withtransmit
7
Applications
Changing/low dielectric Dust/foam/vapor environments Grain elevators/multi-tank installations Tall/narrow silos
8
Designed for ‘Difficult’ Applications
Application
Changing dielectric only affects the intensity of the signal, not the presence of the signal
Not affected by changes in: Temperature Particle size Density Moisture content Very reliable at all lengths down to 1.6 dielectric
constant, some current installations have lower dielectric constants
9
Changing/Low Dielectric
Application
Because looks for the greatest impedance change and not the first impedance change, it can “see” through dust, foam and vapors in a way that technologies that rely on reflection cannot.
Ultrasonic, MIR and through-air radar will all reflect the first product they encounter which will generate a false reading in dust, foam, and vapor environments
10
Dust/Foam/Vapor Environments
Application
One control unit can control up to 24 sensors measuring dissimilar products in different size silos
There are many 48 tank systems and some 64 tank systems currently installed
System architecture allows a customer to add new sensors after original installation, which accommodates growth
11
Grain Elevators/Multi-tank Installations
Application
is transmitted along a specially designed cable that minimizes signal loss Very reliable to 130’, some current applications are
up to 150’ measures a 6” radius
around the sensor cable Not affected by corrugated side walls, cross
members Inherently immune to product coating
12
Tall, Narrow Silos
Control Unit 16 character LCD/ integral
keypad Setup, calibration, diagnostics and
tank level readout RS-232 and modem connection
All keypad functions can be performed remotely
4-20 mA outputs (optional) SPST relays for high and low
level alarm (optional) NEMA 4X molded enclosure
13
Sensors
Several sensor types: Tefzel jacketed steel (standard)
10’ to 130’ -140oF to 300oF
Sensors can be mounted up to 400’ from control unit
Several mountings and terminations available
Determined by application and sensortype
