Stormy weather flows handled with ease with the new 3107 and 3108 ultrasonic transmitters.
Rosemount 3107 and 3108 ultrasonic level transmitters are an important new addition to the existing 3100 Series ultrasonic non-contacting level transmitter portfolio. Using HART communication, they are designed to operate with the Rosemount 3490 Series of universal controllers to provide measurement and control functionality for applications in the industrial and water utilities market.
The 3107 level transmitter has a 12 m measurement range and is a 24 V loop-powered device with 4-20 mA and HART communications. Supplied factory sealed in an IP68 (Type NEMA 6P) rated UPVC housing. The transmitter comes complete with integral cable and stainless steel mounting bracket, ready for installation. When combined with the versatile 3490 controller the system can be used for measurement and control of level, volume (tank contents) or open channel flow using flumes or weirs.
Differential measurements can be made using two 3107 ultrasonic transmitters and a single control unit. The system is easily programmed to display the difference or sum of the two levels, as well as the individual measurements.
The Rosemount Series 3108 is designed specifically for open channel flow measurement when greater accuracy and precision is required. The transmitter features a pre-wired remote temperature sensor and is ideal for water and industrial processing sites looking to improve the accuracy of their open channel flow measurements.
Used in the open air, conventional ultrasonic level transmitters are prone to suffer from inaccuracies caused by ‘solar gain’ when the sun shines directly on them. The 3108 transmitter has been designed to overcome this problem by using the remote temperature sensor wired directly into the transmitter.
Measuring 8 mm diameter x 25 mm long, the compact sensor can easily be located in an appropriately shady spot between the liquid surface and the transmitter. In this way, the system ensures that the air temperature measurement used in the speed of sound calculation is truly representative.
The sensor is hard-wired into the transmitter with a 2 m cable, so there is no additional cabling or set up required and only a single connection to the controller, thus keeping installation costs to a minimum.
The new 3107 and 3108 ultrasonic transmitters are due for release in the latter part of 2010.
Meeting the challenges of tank obstructions interfering with radar
Level Measurement & Control
One of the most challenging applications for non-contacting radar level transmitters is measuring level in tanks with internal obstructions, such as agitators, heating coils, pipes, ladders or baffles. Rosemount non-contacting radar level transmitters from Emerson feature an advanced solution that enables accurate and reliable level measurements in tanks with obstructions.
