FMR10 and FMR20 free space radar level transmitters from Endress+Hauser can be used to measure liquid levels in storage tanks, open basins, open channels, weirs and canal systems. The FMR10 measures liquid levels at ranges up to 16 feet with 0.2-inch accuracy, while the FMR20 measures levels up to 66 feet with 0.08-inch accuracy.

“These transmitters are the best price/performance ratio for straight-forward simple level measurement application,” says Gene Henry, Endress+Hauser’s level product manager. “Its radar technology can be used in situations where ultrasonic transmitters would have typically been used in the past.”

The FMR10 has a 4-20mA output and comes standard with Bluetooth for configuration. The SmartBlue App that runs on any Apple or Android smartphone or tablet will provide secure communications with the transmitter in order to configure or view envelope curves. The encrypted and password-protected Bluetooth wireless connection allows operators to monitor the sensor’s output and perform configurations in hazardous or unsafe locations without exposing personnel to dangerous conditions.

“Certainly the Bluetooth configuration feature is useful and is a timesaver for operators,” says Henry. “The ease of use and cost savings allows an operator to monitor levels in places they typically wouldn’t in the past. That gives them better control over their plant.”

Protection to IP66/68 and NEMA 4X/6P, hermetically sealed wiring, and fully potted electronics eliminate water ingress and allow operation under harsh environmental conditions. Both sensors are available with a flooding protection tube that prevents a loss of echo or signal, even if an overflow condition causes the sensor to be completely immersed.

“It’s a very compact, durable design with the entire inside encapsulated,” says Henry. “That way there is no internal condensation, increasing the unit’s overall life span.”

The level sensors work in process temperatures of -40 to 176 degrees F and process pressures of -14 to 43 psi, are vibration resistant, and have CSA/UL approvals. They are easy to set up, with just three main parameters and a remote indicator solution, resulting in time savings and enhanced safety. The feedback received from those using the transmitters in the field has been overwhelmingly positive.

“Operators love how easy they are to set up and configure, and the price point allows them to monitor tanks and other holding areas that they hadn’t been able to in the past,” says Henry. “The ability to see the envelope curve on a smartphone or iPad via Bluetooth greatly increases the diagnostic capabilities of the transmitters.”
