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
