Any combination of both Ex i and Ex
e electrical circuits can be connected
to the coil and contact connections.
This enables a single relay module
to be used in up to four operating
modes. The 9174 relay module
switches electronically, which makes
it suitable for applications with frequent
switching operations. - R.

A cloud-based software service
for monitoring waterworks
Netilion Water Networks Insights
(NWNI; photo) provides reliable
monitoring of flow, pressure, temperature,
level, water quality and
other measurements. This software

powders in an efficient manner
for quick wet-out and complete dispersion
into low-viscosity liquids. In
a conventional
r otor/stator
mixer, materials
are continually
drawn from
below the mixing
head and
then expelled
at high velocity
through the
stator openings.

supply systems, empowering service
providers and water associations
to manage multiple control and
data sources through a single interface.
These sources include field
devices, industrial controllers, data
transfer components, data recording
and archiving devices, analysis
and forecasting tools, and others.
NWNI provides access to all measurement
data gathered in a water
network and transmitted to the
cloud, whether its users are accessing
the system from a control room
computer, via a laptop at home, on
a tablet in the field, or from a smartphone
on the move. The web-based
interface provides users with complete
system monitoring, and when
limit values are exceeded, or in the
event of failure, it delivers alarms
to users via e-mail, SMS, or push
notifications. - Endress+Hauser,

High-shear mixers for
fine dispersions and emulsions
Batch high-shear mixers equipped
with the Solids/Liquid Injection Manpowders
directly into the high shear
zone and rapidly disperses individual
solid particles into the liquid
vehicle. This method of powder
addition dramatically reduces the
formation of lumps (fisheyes), prevents
floating powders, eliminates
dusting, and accelerates mixing
time, says the manufacturer. The
SLIM can also be used to introduce
minor liquid components and create
fine emulsions. To easily raise and
lower the mixer in and out of the
mix vessel, a floor-mounted design
equipped with an air/oil hydraulic
lift is available. Safety limit switches
prevent operation of the mixer while
in a raised position or without a mix
vessel in place. - Charles Ross &
Son Company, Hauppauge, N.Y.

These flow regulators are now
available in new sizes
The complete product line of this
company's stainless-steel constructed
NSF/ANSI 61-certified
automatic Flo-Trol valves (photo,
p. 30) are now available. The most
recent additions to the Flo-Trol flowregulator
line includes 3/8- through
3-in. models, and standard flow
range offerings from 0.19 to 120
gal/min. With only one internal controlling
mechanism - a Buna-N
self-cleaning orifice - Flo-Trol flow
regulators provide constant flow
over a wide pressure range. FlowFor
