Focus
consumed and reconciled in
terms of weight, this company's
products are designed to
provide direct weight measurement
for bulk materials
stored in silos. However,
because many operators use level
devices and then calculate weight from
data, which may be uncertain, this
company now offers a level measurement
feature on its Solo product line
(photo), which combines the patented
StrainCell sensor with
intelligent
electronics. As a result, users can see
silo weight and level on the display at
the same time. The technology has a
proven accuracy of 1% of full scale for
steel-legged silos and within 3% of full
scale for steel-skirted silos. - Strain

This GWR transmitter has
three times better signal-to-noise
The Eclipse Model 706 guided-waveradar
(GWR) transmitter is said to
be a best-in-class level-control solution.
Designed to provide outstanding
accuracy, reliability and safety,
the latest-generation features include
enhanced signal performance.
The GWR circuitry achieves both a
higher transmit-pulse amplitude and
improved receiver sensitivity, which
leads to a signal-to-noise ratio that
is three times higher than competitive
GWR devices, says the company.
Unlike other GWR transmitters that
use algorithms to infer level readings
in top-of-the-probe dead zones, the
Eclipse 706 measures true level to
within specification all the way up to
the process flange. The new transmitter
also features advanced diagnostics,
with LCD diagnostics conveyed
in realtime waveform and trend data.

A multiparameter transmitter
now includes batch controlling
In March, this company introduced
the second generation Signet 9900
Transmitter, which includes a Batch
Controller option along with the features
of the original version. This
new transmitter supports multiple
parameters that include level, flow,
pH/ORP,
temperature,
pressure and
more - and now
also for batch systems.
Users can convert
their second-generation
9900 transmitter to a
batch controller system by
simply plugging in the new
Batch Module and Relay
Module, thereby maintaining
the product's original

intent of consolidating multiple platforms
into one while increasing their
service level and reducing inventory,
says the company. - GF Piping Systems,

Measurements from remote sites
right to your desktop
AutoLog GSM Wireless Probe is a
new compact and robust device that
performs liquid level measurements
and sends the data to your desktop.
The system uses widely spread GSM/
GPRS networks as communication.
Operators can access data from any
computer's Web browser, anywhere
and at any time. The system does
not require a separate control room,
server PC or special maintenance
staff, so investment and operating
costs are low. Data logging and
sending is possible at programmable
intervals.
Measurements,
alarms,
trends and reports from objects can
be shared by all users. - FF-Automation

An imersion sensor
that measures interfaces
The Turbimax CUS71D ultrasonic immersion
sensor is used for interface
measurements in processes where
suspensions are separated into their
liquid and solid components by sedimentation.
The device can continuously
monitor the separation and
transition zones of the clarification

and settling phases. The sensor uses
a piezoelectric crystal to generate
ultrasound, and measures the time
required for the signal to reach solid
particles in the separation zone, and
then return to the receiver. The sensor
is used with the company's M
CM44x multi-parameter/multiplesensor
transmitters - one sensor
for the CM442, and up to four can
be connected to a CM444 or CM448
transmitter. - Endress+Hauser, Inc.,

Level control is simplifi ed
with non-steady-state tuning
This company's software includes
non-steady-state (NSS) modeling features
for integrating control loops.
These tools are said to provide fast,
simple modeling and tuning of level
controls. Unlike temperature, pressure
and flow, level controls have
different dynamics, and these new
tools make it simple to tune level controls,
even while the level is moving,
says the company. NSS tuning integrates
seamlessly with the company's
PlantTriage and PID Loop Optimizer
software. These tools also provide capabilities
for both tight control and
surge-tank scenarios. NSS modeling
is included with PlantTriage Version
11 and higher, and with PID Loop Optimizer
Version 21 and higher. - ExperTune
