Ultrasonic Level Transmitter works in harsh environments.

Press Release Summary:

Rosemount® 3101, 3102, and 3105 process level transmitters are available with optional corrosion-resistant, glass-filled nylon housing. Rated to IP66/67, non-contact Rosemount 3100 series suits liquid measurement and control applications and provides level measurement up to 36 ft. While 3101 measures level and outputs result as 4–20 mA signal, 3102 and 3105 can calculate distance-to-surface, contents (volume), or open channel flow and output it as 4–20 mA signal and digital HART® signal.

Original Press Release:

Emerson Extends Accurate and Reliable Ultrasonic Level Measurement to Corrosive, Harsh Environments

Rosemount® 3100 series now available with rugged and lightweight plastic housing with Ingress Protection rating up to IP66/67

AUSTIN, TEXAS -- Emerson Process Management has expanded the accurate and reliable measurement capabilities of the Rosemount 3100 Series of ultrasonic non-contacting level transmitters to harsh environments with the option of a plastic (glass-filled nylon) housing. Available on the Rosemount 3101, 3102 and 3105 process level transmitters, the new housing is rugged, lightweight and corrosion resistant.

The plastic housing reduces the weight of the transmitter by one pound compared with the standard aluminium version, making it suitable for installation on extended mounting brackets, or on thin gauge metal tank roofs or plastic tanks. Rated up to IP66/67, it is ideally suited to applications such as water storage installations and waste water and effluent treatment plants.

Rosemount 3100 Series ultrasonic level transmitters provide a cost effective solution for a wide range of liquid measurement and control applications, providing accurate and reliable level measurement up to 36 feet. The local operator interface makes installation and configuration quick and easy. The non-contacting technology with no moving parts enables a long operating life with minimal maintenance requirements.

The series comprises the Rosemount 3101 which measures level, and outputs it as a 4–20 mA signal, and the 3102 and 3105 which can calculate distance-to-surface, contents (volume), or open channel flow, and output the result as a 4–20 mA signal and a digital HART® signal. An integral temperature sensor continuously measures the air temperature around the transmitters. It then computes the speed of sound in air, automatically compensating the calculated distance for temperature effects. In addition, the Rosemount 3102 and 3105 have an optional remote temperature sensor.

The Rosemount 3100 Series is part of a broad range of Rosemount level measurement devices available from Emerson. These include guided wave radar, non-contacting radar, DP and hydrostatic level, ultrasonic, vibrating fork, float switch and specialized conductivity solutions for virtually any level application.
