When Severn Trent of Texas needed reliable level measurement of their customers bleach day tanks, they turned to Flowline. Sodium hypochlorite is a potent disinfectant that’s widely used in municipal drinking water treatment. Somewhat corrosive and highly vaporous, Flowline suggested the use of our pulse radar level sensors in their bleach storage tanks and ultrasonic level sensors in their bleach day tanks. Each ultrasonic sensor provides continuous level data to a local controller, which in turn, displays the day tank inventory, and actuates a fill valve to replenish the tank from bulk storage. Flowline is reliable level measurement.

When Dexter Laundry of Iowa needed reliable level measurement of their customer’s chemical day tanks, they turned to Flowline. Commercial laundries use considerable amounts of cleaning detergents and chemicals. These are delivered in bulk and distributed to their points of consumption in smaller day tanks that feed multiple machines. The chemicals themselves are either sticky and/or corrosive. For this reason, Flowline suggested the use of our ultrasonic sensors that are non-contact, corrosion resistant and completely sealed.

The ultrasonic level sensor provides continuous level data to the PLC, which in turn, monitors the levels and automatically refills each day tank from bulk storage. Flowline is reliable level measurement.

When ACS of New York needed reliable level measurement of their customer’s elevator sump pumps, they turned to Flowline. Sump pumps are located at the bottom of skyscraper elevator shafts to collect and transfer the building’s residual liquids into waste treatment. With a typical composition of water, grease, oil and particulates, their previous capacitance type level sensors would periodically fail due to material build-up, and required costly ongoing maintenance. For this reason, Flowline suggested the use of our non-contact ultrasonic level sensors that are unaffected by such variables.

The ultrasonic level sensor provides continuous level data to the building automation system, which in turn, monitors the elevator shaft sump levels and controls the pumps. Flowline is reliable level measurement.

When a California distributor of water treatment chemicals needed reliable level measurement of their dosing systems, they turned to Flowline. Anti-scalants are commonly injected into process feed water to disperse silica and prevent the build-up of scale that would otherwise damage equipment or dependent processes. The chemicals are sticky and their previous float type level sensors would often fail, requiring periodic cleaning by their truck drivers. For this reason, Flowline suggested the use of our non-contact ultrasonic level sensors that are unaffected by sticky or corrosive chemicals.

The ultrasonic level sensor provides continuous level data to the chemical feed controller, which in turn, displays the tank levels and actuates low level alarms for replenishment. Flowline is reliable level measurement.

When a California shipyard needed reliable level measurement for their customer’s fuel, water and greywater holding tanks, they turned to Flowline. Yacht manufacturers typically install float type magnetostrictive level sensors that fail over time due to material build-up, resulting in fuel shortages and greywater overflows. For this reason, Flowline suggested the use of our non-contact ultrasonic level sensors that are unaffected by sticky diesel or coating wastewater. The shipyard has since standardized on this solution and are now retrofitting 1-2 yachts per month.

The ultrasonic level sensor provides continuous level data to the multi-tank level controller, which in turn, displays tank levels and actuates high or low level alarms. Flowline is reliable level measurement.

When a California bleach manufacturer needed reliable level measurement of their diatomaceous earth mixing tanks, they turned to Flowline. A fine white powder of up to 90% silica, diatomaceous earth is mixed with water and injected into filtration systems to improve filter performance. Very sticky, the slurry coats everything it comes into contact with, including their failing high level switches. For this reason, Flowline suggested the use of our non-stick, PFA Teflon® ultrasonic level switches that are unaffected by coating build-up. The ultrasonic switch is mounted on Switch-Pak™ to the desired high level alarm position.

The 12-36 VDC powered sensor provides a 1A relay contact to the PLC, which in turn, closes the fill valve and actuates an audible alarm. Flowline is reliable level switching.

When a US municipality needed reliable level measurement of their polymer mixing tanks, they turned to Flowline. Polymer is widely used in wastewater treatment to coagulate suspended solids, producing large curds of floc or solid material, which can then be easily removed from the process. Granulated or emulsive polymer is diluted with water, blended, and injected into the process with a high viscosity metering or variable speed pump. A polymer mixing tank typically holds 1-2 days of product before a new batch must be made up, and level measurement of this sticky media is critical to the operator. For this reason, Flowline suggested the use of a non-contact ultrasonic level sensor. The result is reliable polymer level measurement. 

Here, an EchoPod ultrasonic level transmitter is safely mounted above the polymer solution. Despite being located next to the tank side wall and mixer shaft, the sensor’s measurement is unaffected due to its industry leading 2? (5 cm) beam width. The two-wire, 4-20 mA signal output is connected to the SCADA for level monitoring, and the integral relays actuate a high and low alarm. Flowline is reliable level measurement.

Powder coated metal parts are more durable than painted parts and are the required coating for many industrial, automotive and consumer products. During the powder coating process, fine color pigment and resin particles are electrostatically sprayed on to grounded metal parts, which are then baked to a hard smooth finish. But before any parts can be coated, they must be thoroughly cleaned to remove grease, oil, dirt, welding scales or metal oxides that would otherwise affect the finish quality. 

This is achieved in multiple stages consisting of degreasing, etching, de-smutting and the final phosphating of the substrate with phosphoric acid to enhance the bonding strength of the metal surface. Based on the parts finish requirements and size, diluted acid is applied by either dipping or spraying. Once rinsed and dried off, the clean parts are ready for powder coating and the oven. At this US defense contractor, an EchoPod ultrasonic level transmitter is installed in each of their phosphoric acid day tanks that are located near the ceiling to maximize floor space. The non-contact, corrosion resistant sensor was selected because of it’s industry leading 2? dead band that enables near full capacity utilization of small tanks. Flowline is reliable level measurement.

An estimated 21,594 public municipal water treatment plants provide wastewater collection, treatment and disposal service to 226.4 million people in the United States. Collectively, they reclaim, treat and supply about 1 billion gallons of non-potable water per day to our nation. Most of which is used to irrigate golf courses, public parks and open green space. At the start of the treatment process, water is separated from solid waste inside a sludge tank separator. As water passes through the first stage, heavier sludge and particulate settles to the bottom of the tank, leaving only fine suspended solids. 

In the second stage, the water is passed through a mechanical screen filter where micro-organisms further digest organic matter, converting it to odorless liquid and gas. At this treatment plant, one EchoPod ultrasonic level transmitter is measuring the water level before it passes through the screen filter, and a second EchoPod is measuring the water level after the screen filter. When the differential becomes significant, the SCADA will actuate an alarm indicating that its time to clean the filter. Flowline is reliable level measurement.

Everyday, municipalities treat, store and deliver, millions of gallons of potable water to support our countries insatiable water requirements. The most common types of water storage include reservoirs, tanks and towers. Once treated, water is pumped into storage for use by the local community. At this US water storage facility, an EchoSonic ultrasonic level transmitter is installed in the tank top. The non-contact sensor provides continuous level data to the SCADA, which in turn, indicates the amount of water and/or space available for additional water to be pumped into the tank.

The data is remotely monitored by the treatment plant, and used in the execution of their water treatment and storage operations. Accuracy is important give the size of the tank, where a 1” change in level equates to 70,000 gallons of water. EchoSonic is reliable water storage level measurement.
