Control the level
in hazardous areas
Omega
Engineering
The Fisher L2e level controller
(photo, p. 26) uses a rugged
the material.
It also
adds stability in turbulent
tanks. For installations
where the level
sensor is threaded into
a tank, users prefer to
install conduit to protect
the cable from the work
environment. AST 4500,
4510 and 4520 level sensors
are Class I Div. 1
intrinsically safe, Group
threaded, screw-off cover that allows
easy access to internal components
and an FDA-recognized powder coat
finish. - BinMaster, Lincoln, Neb.

Submersible transmitters that
measure depth or level
The PX709GW Series submersible
level/depth transducers and transmitters
(photo) are designed to make precision
level or depth measurements in
fresh water or liquids that are compatible
with 316 stainless steel. The standard
device has an accuracy of 0.20%,
and optional high-accuracy models
are available with 0.8% accuracy.
They are available with lightning and
surge protection, and have outputs of
4-20 mA, 0-5 V or 0-10 V. - Omega
Engineering, Inc., Stamford, Conn.

Conduit fi ttings protect
this level sensor's cables
Since last August, this company has
supplied its liquid level sensors (photo)
with ½-in. NPT male conduit fittings
before the cable interface. This is beneficial
if the sensor is going to be exposed
to a liquid not compatible with
C and D when installed with a barrier
as well as ABS (American Bureau of
Shipping) certified. Pressure ranges
are available as low as 0-1 psi (27.68
in. water column) - American Sensor
Technologies, Inc., Mt. Olive, N.J.

Monitoring tanks remotely
through the cloud
Tank Cloud Remote Monitoring (photo)
is a cost-effective remote tank-levelmonitoring
system that enables users
to monitor facilities and processes
from anywhere with an Internet connection,
24 hours per day, 7 days per
week. Using the company's proprietary
remote level sensors and modules,
or any sensor with a 4-20-mA
output, Tank Cloud users can remotely
monitor level, pressure, temperature,
flow, pH and other process variables
through an easy-to-use online interface.
Sensors and input modules connect
to the user's network via an Ethernet
cable and transmit data via the
user's internet connection, whether
landline, cellular, radio or satellite. On
Tank Cloud remote monitoring Web
portal, operators and managers have
ready access to realtime and historiforce-balanced
displacer sensor
to detect the level of a single liquid
or the interface of two liquids.
The controller's new knife-edge sensing
design combines with aerospacequality
switch technology to provide
rugged, reliable and accurate level
control, says the company. The L2e
zero and span adjustments enable tuning
for a wide variety of level-loop applications.
Additionally, the controller
is certified for use in hazardous areas
and is NACE-compliant for " sour " service.
By scanning the QR code on the
inside cover of the L2e, instrument
technicians have access to 24/7 field
support for setup, calibration and loop
tuning. - Emerson Process Management,

This switch has a SIL2 rating
and many approvals
The FLT93 Series FlexSwitch (photo,
p. 26) is a precision flow/level/temperature
switch for use in liquid, air,
gas or interface service. Suitable for
oil-and-gas upstream production or
downstream refining,
storage and
distribution, the FLT93 Series FlexSwitch
provides dependable reliefvalve
monitoring and flare-gas flow or
leakage detection. The device is said
to be the most advanced heavy-duty
thermal-dispersion technology flow
and level switch available. SIL2-rated
for ultra reliability, the device also has
Ex agency approvals for the entire instrument,
including FM, FMc, ATEX
and IECEx. - Fluid Components International,
LLC, San Marcos, Calif.
