MTS Systems Corp. Sensors Division has been working with OleumTech Corporation to provide their customers with a solution that allows the customer to monitor tank levels via the Web. MTS Sensors provides the tank measurements and the OleumTech wireless monitors transmit the databack to the control room, where a Modbus controller with Ethernet output passes the data onto the Web. In the end, the customer is able to open a webpage and pull up the latest measurement at anytime.
"The benefits for the customer from this solution are tremendous. The customer saves money on conduit, cable, and has the added convenience ofallowing anyone the ability to check tank levels from anywhere," saidLee Aiken, MTS Product Marketing Manager. "MTS and OleumTech are veryexcited about the success customers are having with this solution andwe are working together to create additional solutions."
MTS Sensors uses its Level Plus model MG liquid level transmitter to measure the level in storage tanks. The tank level is transmitted via Modbusto the OleumTech LevelMate Monitor that sends the measurement to thecontrol room where the OleumTech DataHub is located. The output from the DataHub is connected to a Fieldbus controller that places the information on the Internet. The customer can open the website and poll theunit to find out the last collected measurement. The user can customize the update time of the radios and the web interface.
The intended application for the current model MG transmitter and LevelMate Monitor solution is for tanks that have line power from a local sourcebut don’t have communication lines back to the control room. MTS has found several locations where the control room is located hundreds of yards away from the tanks and the expense of running conduit the full length has inhibited the use of automatic tank gauging on the tank. However, there is no need for battery-powered gauges and/or radios sincepower is located throughout the facility. The solution provided by MTSand OleumTech allows customers to reap the benefits of automatic tankgauging without having to endure the costs of running conduit.
Customers choose the model MG transmitters due to its ability to provide 3 in 1 measurement of the product level, interface level and temperature along with offering volume outputs from 100 point strap tables.It has built a reputation of accuracy, reliability, simple installation, and field replacement. Every gauge is built custom to the application and is available in lengths from 5 to 18m. The transmitter can operate on 12 or 24Vdc power via its 4-wire Modbus connection.
