Two transmitters added to wireless family
Two discrete-input transmitters have been added to the family of XYR wireless devices: The STXW 500 and the STTW 401 transmitters can convert any measurement device with a contact-closure switch input into a wireless input, enabling manufacturers to decrease costs and improve efficiency by wirelessly monitoring more processes at their plants.
The transmitters are suited for applications such as wirelessly monitoring level switches, pump status, and system alarms.
The new devices can transmit signals from as many as three contact switches. The STXW 500 transmitter accepts three discrete-digital inputs while the STTW 401 transmitter accepts a thermocouple input and two discrete-digital inputs. Both transmitters carry intrinsically safe approvals for use in hazardous areas from FM Global and the Canadian Standards Association.
These new XYR 6000 transmitters enable plants to convert existing measurement devices to wireless solutions without needing to replace the equipment.
The STXW 500 and STTW 401 transmitters complement the other wireless transmitters in the firm’s XYR 6000 product line, which includes: absolute and differential pressure transmitters, temperature transmitters, analog transmitters, corrosion monitoring transmitters, and gauge pressure transmitters.

New on line control valve sizing program
FlexSelect is a new control valve size selection process for this firm’s rotary control FlexStream technology.
This on line program (http://www.mogas.com/Valvesizing/login.aspx) can help users determine the appropriate valve and trim configuration for their quarter-turn control valve needs.
After inputting the appropriate data into the program, an estimated sizing configuration will be generated that, if given the proper data, will show the client the recommended characteristics to meet the requirements for their application.
The program is for the use of control valve applications using proprietary FlexStream technology.
Control valves utilizing FlexStream force fluids or gases through a series of right angle turns, providing the ability to control each stage of pressure letdown, while removing kinetic energy from fluids and lowering pressure in a controlled manner.
The trim element delivers pressure reduction, velocity control, and noise reduction. Additionally, the tortuous paths in the trim help to combat cavitation and flashing.
