EchoPulse® and EchoPro® Radar Liquid Level Transmitters
Harrington’s commitment to exceptional customer service begins with its relationships. We partner with the industry’s top-tier manufacturers to ensure our customers receive the best-in-class products, keeping their process systems running smoothly.
We are excited to share the EchoPulse® and EchoPro® Radar Liquid Level Transmitters from our supplier partner, Flowline. These rugged non-contact sensors were designed to suit best challenging bulk tank, process, or sump applications.
EchoPulse (general purpose with 4-20 signal output) & EchoPro (hazardous with HART & 4-20 signal output) address process measurement applications where vapor, temperature, pressure, and/or foam are present that will attenuate the signal responses and/or distort the measurement performance of other level technologies, i.e., ultrasonic, hydrostatic pressure, floats, capacitance and/or conductance.
The difference is in the technology – the radar sensor emits a 26 GHz or 6.3 GHz RF pulse from the base of the antenna. This pulse travels through the free space, reflecting against the liquid dielectric materials and returns back to the antenna. The sensor then measures the pulse time of flight and translates it into liquid level distance. Measurement by pulse radar is unaffected by process conditions that cause other sensing technologies to fail or require ongoing maintenance.

Flowline Echosonic II Ultrasonic Level Transmitter
The Flowline Echosonic II ultrasonic level transmitter is a general purpose two-wire ultrasonic level transmitter that provides non-contact measurement for liquid levels ranging from as little as 4″ up to 32.8′ (10cm to 10m). The Flowline Echosonic II GP ultrasonic level transmitter and is well suited for challenging ultrapure, corrosive, slurry, or waste liquids in atmospheric bulk storage, day tank, waste sump, process vessel, IBC tote, 55-gallon drum, and waste sump applications.
Changing the Flowline Echosonic II ultrasonic level transmitter from its factory settings is simple with Flowline’s WebCal software, an innovative PC user interface that provides fast and accurate configuration. An optional Fob USB Interface tool is required (Fobs are universal and can configure multiple transmitters).
Flowline DeltaSpan® Hydrostatic Level Transmitters
Flowline DeltaSpan transmitters provide reliable continuous level measurement for clean, dirty, and corrosive liquids. Designed for tanks, wells, and lift stations, each model converts liquid head pressure into a stable 4–20 mA output with built-in temperature compensation and surge protection. Submersible and external-mount options support a wide range of industrial and chemical applications.
DeltaSpan External-Mount Models (LD30 & LD37)

Compatible Displays & Controllers
- DataLoop Indicator – Loop-powered 4–20 mA display with optional relays.
- DataView Controller – 4-relay or 2-relay controller for local alarms or pump control.
Flowline AX1X Thermo-Flo Flow Controller
The Flowline AX1X Thermo-Flo Flow Controller provides reliable no or low-flow detection of relatively clean non-coating media with a 16A compact flow controller for pump or process protection. The optional flash alarm brings attention to low-flow alarm conditions. Liquid examples includes water and sulfuric acid.
A common problem with metering pumps in flow applications is the characteristic of the output flow. The pulsating flow makes it difficult for flow switches to get an accurate and consistent flow rate because they are not able to see a reliable flow output. The FlowlinePulsePoint fitting is designed to stabilize the pulsing flow for the Thermo-Flo flow switch. The cylindrical chamber creates a mini-vortex that creates a relatively constant flow. The Thermo-Flo flow switch will be able to read the flow and provide an accurate and low-cost flow switch. The Flowline Pulse Point fitting is ideal for use in metering pump applications.
Flowline EchoBeam® — Advancing Precision with 80GHz Frequency for Unparalleled Level Detection
EchoBeam, an advanced non-contact radar transmitter, seamlessly combines radar’s high-performance attributes with the cost-effectiveness of ultrasonic technology. Operating at 80 GHz, or W-Band, EchoBeam utilizes Frequency-Modulated Continuous Wave (FMCW) radar technology within the 75 to 85 GHz frequency range. This innovative approach significantly enhances the Signal-to-noise ratio compared to traditional Pulsed Wave radar transmitters, distinguishing EchoBeam by the absence of a dead band—a characteristic feature of FMCW radar that sets it apart from pulse radar systems.
EchoBeam demonstrates remarkable resilience, remaining unaffected by elements like foam, vapors, or fumes that typically challenge ultrasonic counterparts. In essence, EchoBeam represents a cutting-edge solution, seamlessly integrating precision, reliability, and versatility into a single radar transmitter.
Operating at 80 GHz, EchoBeam excels in providing exceptional accuracy and resolution, making it the ideal choice for applications that demand precision. This frequency not only ensures high precision but also has the capability to penetrate non-metallic materials, facilitating level detection without the need for tank intrusion. Additionally, the 80GHz design effectively eliminates the dead band, contributing to enhanced performance across various scenarios.
It’s essential to note that as the liquid or solid level approaches the sensor, there may be a reduction in accuracy, resulting in a coarser measurement. Despite this consideration, EchoBeam’s 80GHz frequency remains a versatile solution for applications requiring both precision and non-intrusive level detection.
- Easy to Configure – EchoBeam uses the LevelTap App that connects your Smartphone directly to the device.
- Small Packaging – allows for installation in smaller tanks plus retrofitting from older technologies is easy.
- Small Dead Band – allows for installation in smaller tanks with the ability to fill to a greater volume in the tank (just don’t touch the antenna).
- Improved Resolution – not only is accuracy improved, but filtering out false targets is easier for EchoBeam.
- Application Friendly – the breadth of applications is greater than any other technology or previous releases.
- Works on Liquids or Solids – Note: the maximum range for solids is approximately ½ the max. range of liquids.
