  • Contact Level Sensors
  • Liquid Level Switches and Controllers

    Include ultrasonic level switches, optic leak detectors, capacitance level switches, USB hubs, vertical buoyancy switches, vibration level switches and more.

  • Noncontact Level Sensors

    Include noncontact ultrasonic level sensors used to measure the level of liquids in tanks, reservoirs or other containers by emitting an ultrasonic pulse that travels through the air & reflects off the liquid surface to the sensor.

  • Optical Liquid Sensors

    Level sensors installed in the interstitial space between the inner and outer walls of the tank for detecting the presence of liquid in this space and subsequently indicate a potential leak.

About FLOWLINE

The company's product catalogue includes liquid and solid-level transmitters, ultrasonic sensors, level switches, controllers & indicators, fittings & enclosures and parts & accessories. Flowline's level switches offer reliable liquid-level detection in reservoirs and tanks and allow pump automation to drain excess liquid out of the system. They are made from polypropylene and PVC, which makes them lightweight & submersible, as well as safe to use with harsh and corrosive liquids. They are compatible with different counterweight and cable hanger installations to provide an accurate pivot point for these floats when submerged completely in liquid.

Things To Consider

Cross-Reference Alternatives

Flowline MPNs cross individual references to the equivalent Honeywell and Madison level switches and sensors. So, if you're looking for a competitor item that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent Flowline products available.

Shipping

These Flowline products range from small to large sizes. They may require careful packaging as some items might get damaged while shipping. Hence, these Flowline items are delivered by courier shipment and air freight for minimum downtime.

FLOWLINE Competitive Advantages

Flowline Filter Housing

This filter housing is made of stainless steel, making it suitable for various industrial, commercial and OEM applications. It has fabricated construction with a cover opening that can easily adapt to different piping layouts. Its adjustable mounting legs allow easy installation and the integral cover handle makes it easier to open / close the cover. The housing is available in carbon steel and Type 304 / 316 stainless steel materials for use in corrosive environments and has smooth, bead-blasted finish to allow easy cleaning of the interior.

Frequently Asked Questions

What is the use of an ultrasonic sensor?

An ultrasonic liquid sensor is an instrument used for measuring the height of a liquid and converting it to an electrical signal. The signal output is then utilised via supporting instruments to display, monitor, log or control the liquid level.

What is meant by a dead band?

Dead band is the air gap distance in front of the transducer that a sensor cannot measure.

What is the advantage of using pulse radar in non-contact sensors?

Pulse radar measures powders, grains, aggregates, building materials or pellets in silo, bin, stockpile, crusher or transfer station applications. It is also unaffected by process conditions, like dust, material build-up or temperature that cause other sensing technologies to fail.
