When
a US chemical distributor needed reliable level measurement of their nitric
acid storage tanks, they turned to Flowline. Nitric is a highly corrosive
oxidizer that’s widely used in the production of fertilizers, electronics,
explosives and specialty compounds. The company had previously applied
ultrasonic level sensors for corrosion resistance, but they experienced
intermittency due to the thick nitric acid vapor that would absorb the acoustic
signal. For this reason, Flowline suggested the use of pulse radar sensors whose
RF signal is unaffected by vapor. The result is reliable nitric acid level
measurement. Here, an EchoPulse radar level transmitter is flange mounted on
top of a 15?, Teflon® lined FRP bulk storage tank. The rugged PTFE antenna
protects the sensor for lasting, reliable service with corrosive media
including harsh nitric and hydrochloric acids. The 4-20 mA signal is connected
to the PLC for tank inventory monitoring and alarms. |

When
a municipal wastewater treatment plant needed reliable level measurement of
their clarifiers, they turned to Flowline. For many US operators, ferric
chloride is the coagulant of choice due to its efficiency in water treatment
clarification and dewatering applications. When agitated, ferric chloride bonds
to and absorbs phosphorous waste material, before floating to the liquid
surface as a blanket of reddish brown flocculent. From a level perspective,
ferric chloride has the additional challenge of being coating and corrosive.
For this reason, Flowline suggested the use of our non-contact pulse radar
sensors that are unaffected by surface foam. The result is reliable ferric
chloride level measurement. Here, an EchoPulse radar level transmitter is
bracket mounted to an arm and suspended over the clarifier. The IP68 sensor was
easily configured using its remote push button display module, and the 4-20 mA
signal is connected to the SCADA for level alarms and pump control. |

When a Virginia
equipment manufacturer needed reliable level measurement of their polymer
mixing and feed systems, they turned to Flowline. Organic flocculants are
widely used in water treatment for clarification, thickening and dewatering.
Their polymer chains attract suspended solids and form flocs or groups that
precipitate during settling, and thus leave clear liquid behind. Polymer
solution is sticky and the company had problems with their previous conductance
level sensors that required ongoing maintenance due to coating build-up. For
this reason, Flowline suggested the use of our non-contact, ultrasonic level sensors
that are unaffected by sticky or viscous liquids. The ultrasonic sensor provides reliable level data to the PLC, which in turn, monitors the mix tank level, and manages the polymer batch make-up and blending process. Flowline is reliable level measurement. |

When a US chemical
distributor needed reliable level measurement of their oil field chemical feed
tanks, they turned to Flowline. Surface water and downhole fluids often combine
into salty, brackish solutions that negatively affect well production and
equipment. To address this, antiscalant chemicals are injected into the well to
reduce salts and other contaminants. But they’re also corrosive, and over time
the operators had experienced high failure rates with their pressure level
sensors due to corrosion. For this reason, Flowline suggested the use of our
non-contact, reflective ultrasonic level sensors that are packaged in PVDF, and
feature our proprietary Reflective Technology™ that delivers reliable level
measurement in condensing tank environments. Each ultrasonic sensor
provides reliable level data to the SCADA, which in turn, monitors the levels
and transmits inventory data to a logistics center for truck routing and
resupply. Flowline is reliable level measurement. |

When the Sutton Brook
superfund remediation site in Tewksbury, Massachusetts needed reliable level
measurement of their chemical feed systems, they turned to Flowline. For
decades, the landfill served as a hazardous waste dump, and was filled with
chemical and metal contaminants that had leached into the groundwater. During
the clean-up project, chemical feed systems were installed in and around the
site for water remediation and odor control. The operators had experienced
corrosion and coating problems with their previous float level switches. For this reason,
Flowline suggested the use of our non-contact, ultrasonic level sensors that
are packaged in corrosion resistant PVDF. Each compact ultrasonic sensor
provides reliable level data to the PLC, which in turn, monitors the levels and
automatically refills each chemical feed tank from bulk storage. Flowline is
reliable level measurement. |

When Mercy Medical
Center in Iowa needed reliable level measurement of their cooling towers, they
turned to Flowline. As water cascades down the tower, heat is released through
evaporation and the residual water collects in sumps, prior to recirculation.
Level is measured to control the recirculation and addition of makeup water to
the system. The operator had experienced ongoing problems with their previous
float level switches due to scaling material build-up. For this reason,
Flowline suggested the use of our non-contact, ultrasonic liquid level sensors
that are unaffected by common variables such as scaling or corrosion. Mounted
in a still well, the IP68 ultrasonic sensor provides reliable level data to the
PLC, which in turn, monitors the sump level and controls the recirculation pump
and fill valve. Flowline is reliable level measurement. |

When
Zimmer of Indiana needed reliable level measurement of their nickel
electroplating lines, they turned to Flowline. As a manufacturer of hip and
knee replacement joints, the finish quality and tolerances of their plated
parts are critical. Their previous float level switches would periodically fail
due to corrosion attack, resulting in significant scrap loss. For this reason,
Flowline suggested the use of our non-contact, ultrasonic level sensors that
are packaged in corrosion resistant PVDF. Each ultrasonic sensor provides
continuous level data to the PLC, which in turn, monitors the bath levels and
actuates a valve to systematically refill each bath. Flowline is reliable level
measurement. |

When
the largest radiological laundry company in North America needed reliable level
measurement of their wastewater treatment tanks, they turned to Flowline. They
collect, decontaminate and launder protective clothing from the Department of
Energy nuclear power plants and military facilities. Given the extreme nature
of wastewater in their tanks, they had four level measurement requirements. The
sensors must be reliable, maintenance-free, non-contact and intrinsically safe
for certain site locations. For this reason, Flowline suggested the use of our
intrinsically safe, non-contact ultrasonic level sensors that are ideal for
wastewater. The ultrasonic sensor provides continuous level data to the PLC,
which in turn, monitors each tank and controls the wastewater treatment
process. Flowline is reliable level measurement. |

When ChemFrac of North
Dakota needed reliable level measurement of their brine backflow recovery
tanks, they turned to Flowline. These tanks collect the residual wastewater
that returns back to the surface over time, representing 15%-40% of the total
fluids injected into the well. Backflow tanks are normally located within a
hazardous area, and the water is a muddy blend of salts, dirt, clay and
chemical. For this reason, Flowline suggested the use of our explosion proof,
non-contact ultrasonic level sensors that are unaffected by such media. The ultrasonic sensor
provides continuous level data to the PLC, which in turn, monitors each tank
and actuates a high and low level alarm to alert the operator. Flowline is
reliable level measurement. |

When
PatchMix of California needed reliable level measurement of their cold patch
asphalt mix tanks, they turned to Flowline. Quickly emulsified in water and
blended with aggregate, cold mix asphalt is a highly effective patching
material. But when dry, it permanently coats equipment including the tanks,
mixers and level sensors. For this reason, Flowline suggested the use of our
non-contact ultrasonic level sensors that are unaffected by sticky media. The
ultrasonic sensor provides continuous level data to the controller, which in
turn, monitors the mix tank and actuates a high and low level alarm to alert
the operator. Flowline is reliable level measurement. |
