Drinking Water Fluoride Tank Ultrasonic Level Transmitter______________________________________________________ When a Southwest municipality needed reliable level measurement of their fluoride chemical feed tanks, they turned to Flowline. The treatment plant injects a 24% solution of fluorosilicic acid into their distribution system to fluoridate drinking water. A new chemical feed tank was needed, and the plant wanted a total solution including corrosion resistant level measurement, indication and fittings. For this reason, our distributor partner specified our PVDF non-contact ultrasonic level sensor, level indicator, NEMA enclosure and fitting with the tank. One call, single source, reliable tank systems. The ultrasonic sensor provides reliable level data to the level indicator which displays in gallons and alarms for acid replenishment. Flowline is reliable level measurement. |
Chemical Distributor Tank Radar Level Transmitter______________________________________________________ When a Midwest chemical distributor needed reliable level measurement of their solvent and acid storage tanks, they turned to Flowline. The firm receives bulk deliveries at their transloading station where chemicals are pumped from tanker railcars into large storage tanks. There the plant engineer said they needed to replace failing level sensors and stated his requirements. “We want a reliable, non-contact and highly corrosion-resistant sensor that can be applied with acids, caustics or hazardous solvents with a dielectric value ≥ 2.0. Last, if this can be achieved with a single sensor, that’s our preference.” For these reasons, Flowline suggested our intrinsically safe radar sensor that’s flange mounted with a PTFE antenna shield. The radar sensors provide reliable data to the tank indicators and PLC for inventory monitoring. Flowline is reliable level measurement. |
Sulfuric Acid Storage Radar Level Transmitter______________________________________________________ When a Gulf Coast chemical distributor needed reliable level measurement of their acid storage tanks, they turned to Flowline. The firm receives, stores, dilutes and delivers sulfuric acid to clients from their trucking terminal. There they cold store sulfuric in concentrations as high as 99% with an air purge and nitrogen blanket above the liquid. The I&C engineer was dissatisfied with previous ultrasonic level sensors that performed erratically due to vapor and nitrogen signal attenuation. He wanted a reliable, non-contact, corrosion-resistant level sensor that’s not influenced by tank vapor or foaming. For these reasons, Flowline suggested our radar sensor that’s unaffected by such media or process variables, and directly flange mounts with a PTFE antenna shield. The radar sensors provide reliable data to the PLC which monitors the sulfuric tanks and controls the terminal functions. Flowline is reliable level measurement. |
Chemical Pump Protection Thermal Dispersion Flow Switch______________________________________________________ When a Southeast municipality needed reliable chemical process and run-dry pump protection, they turned to Flowline. Diluted chemicals are transferred from storage tanks to day tanks via magnetic drive pumps. But each year, chemical outages de-rail the treatment process or damage costly pumps. To mitigate this, the I&C engineer requested a solid-state corrosion-resistant flow switch that would reliably indicate no or low-flow and empty-pipe conditions. For these reasons, Flowline suggested our thermal dispersion flow switch that’s constructed of PP or PVDF with an adjustable set point, LED flow indicator and selectable NO or NC relay output. The flow switch provides reliable flow detection to the SCADA which controls chemical transfer and water treatment. Flowline is reliable switching. |
Brine Make Up Tank Pressure Level Measurement______________________________________________________ When a Northwest municipality needed reliable level measurement and control of their brine make up tank, they turned to Flowline. The water plant creates brine and then converts it into chlorine via electrolysis. The I&E technician arrived to find that the mechanical contractor had used all available mounting ports on the fiberglass tank, and there was nowhere to install his specified level sensor. He needed ideas as to how he could measure the level without cutting another hole in the tank-top? For this reason, Flowline suggested the use of our external pressure sensor, mounted on the outside of the inspection port with a valve in between for easy removal and inspection. The external pressure sensor provides reliable non-invasive level data to the controller which monitors the tank and alarms when high or low. Flowline is reliable level measurement. |
