Flowmeter Uses Helical Sonic Pattern

Alpharetta, Ga.— The Sitrans F flowmeter can measure both laminar and turbulent flow. A helix shaped ultrasonic guidance system provides higher accuracy than one or two dimensional signals. Measurement is based on a tracking principle where the difference between echo times is analyzed upstream and downstream. Reflectors integrated into the tube wall deflect the sound beam laterally, and after reflecting several times, send it to the receiving transducer. The sound conduction pattern produced covers the entire cross section area of the flowtube and is claimed to be largely independent of the Reynolds number. Accuracy of

Hot Metal Detector is Multifunctional

Highland Heights, O.— The HotSpot multisetpoint hot metal detector (HMD) is said to be the first sensor of its type to offer field-selectable temperature setpoints. It simplifies stocking requirements because its adjustability makes it a "one-sensor-fits-all" product. The HotSpot is forgiving in certain applications where factors, such as background temperatures, are not as warm or cool as originally envisioned. The Hotspot claims to be the first static HMD that is PLC compatible. Its low leakage current of &1.7 mA eliminates the need for shunt resistors during installation or operation. The sensor's maker, Namco Controls, says the sensor is the first of its type that can be serviced.

Houston, Tex.— DMCplus accounts for interactions among multiple variables, overcomes process disturbances, and predicts future performance using a mathematical model of the process' behavior. DMCplus can collect input/output data from the plant, build a multivariable model of the overall process, simulate the plant's behavior, and control all of the process variables in real time. The online components of DMCplus run on a standalone computer connected to a distributed control system that collects measurements from the plant's sensors and sends control commands to the actuators. DMCplus also uses a linear-programming-based optimizer to identify where setpoints should be in order to run a process most profitably.
