FLOWLINE

FLOWLINE is a manufacturer of liquid level measurement and control instrumentation, headquartered in the United States. The company's product line focuses on non-contact and contact level sensing technologies, including ultrasonic, radar (guided wave and through-air), and conductive level switches, as well as level transmitters and controllers. FLOWLINE products are designed for industrial applications involving corrosive, ultrapure, or viscous liquids, and are commonly used in chemical processing, water and wastewater treatment, oil and gas, and food and beverage industries. Key technical attributes include accuracy ratings (e.g., ±1 mm for ultrasonic models, ±3 mm for guided wave radar), probe materials such as polypropylene and 316 stainless steel, body materials like aluminum, and mounting options including vertical orientation with 3/4 in NPT connections. Output configurations typically range from 4 to 20 mA, with voltage options of 12/36 V DC. FLOWLINE also offers accessories such as reducer bushings and level controllers with DIN rail or panel mount options, LED displays, and relay outputs. 3G Electric supplies a range of FLOWLINE sensors, transmitters, and controllers, supporting plant engineers and maintenance managers with specification-grade components for level monitoring and control systems. The inventory includes submersible ultrasonic level switches, coaxial and rod guided wave radar sensors, and level transmitter displays with digital readouts. These products are suited for applications requiring reliable level detection in challenging media, with IP-rated enclosures and materials selected for chemical resistance. 3G Electric's catalog provides detailed specifications, enabling procurement specialists to match FLOWLINE equipment to process requirements without reliance on marketing claims.

Frequently asked questions

Common questions about FLOWLINE from 3G Electric.

What types of liquid level sensors does FLOWLINE offer?

FLOWLINE manufactures ultrasonic, guided wave radar, and conductive level sensors. Ultrasonic models are non-contact and suitable for corrosive or ultrapure liquids, with accuracy up to ±1 mm. Guided wave radar sensors, available with rod or coaxial probes, provide ±3 mm accuracy and are used in applications with foam, vapor, or turbulence. Conductive level switches are designed for conductive liquids and offer simple on/off control.

What are the typical output options for FLOWLINE level transmitters?

FLOWLINE level transmitters commonly provide a 4 to 20 mA analog output, with supply voltages of 12/36 V DC. Some models also support digital communication protocols. The output configuration is typically 4-wire, and the transmitters are designed for integration with PLCs, SCADA systems, or FLOWLINE level controllers.

Can FLOWLINE guided wave radar sensors be used in high-temperature applications?

FLOWLINE guided wave radar sensors are rated for operating temperatures up to approximately 149°F (65°C) for standard models, with some variants supporting higher ranges. The stem and probe materials, such as 316 stainless steel, provide resistance to thermal stress. For specific temperature limits, refer to the datasheet for the exact model number.

What mounting options are available for FLOWLINE level controllers?

FLOWLINE level controllers are available in DIN rail mount and panel mount configurations. DIN rail models, such as the LC52-1001, are designed for enclosure mounting and feature LED displays with 3.5 digits. Panel mount models, like the LI55-1211, offer 6-digit LED displays and are suitable for front-panel integration. Both types support relay outputs for alarm or pump control.

Are FLOWLINE ultrasonic level sensors suitable for use with corrosive liquids?

Yes, FLOWLINE ultrasonic level sensors, such as the LU10-1405, are designed with polypropylene probe material and are rated for use with corrosive liquids. The non-contact measurement principle eliminates direct contact with the media, and the sensor housing is constructed from materials resistant to chemical attack. These sensors are commonly used in chemical storage tanks and wastewater applications.
