Abstract: The data transmission system has a Bluetooth transmitter/receiver unit in each device (11,12) for data transmission in the ISM band with a carrier frequency of the order of 2.4 GHz. Each transmitter/receiver unit is connected to a directional radio antenna (21,22). The devices are more than 50 m. from each other and at least one device is connected to further devices via a network.

Abstract: A photoacoustic effect is used in order to measure a flow rate of a flowing medium (M), in-particular of natural gas. A light emitter (1) is used to produce in the medium (M) a sound wave (S) which is transmitted by the medium (M) and detected by a sound detector (2). The light emitter (1) is less exposed to the medium (M) than a diaphragm such as used in the ultrasonic method.

Abstract: Oil-in-water measurement involves feeding oil-contaminated water to a measuring cell (7) and measuring an electrical impedance signal (19). The cell is calibrated and/or flushed automatically at periodic intervals. An Independent claim is included for an oil-in-water sensor, which has means for self-calibration and/or self-flushing of the measuring cell, and a controller for their automatic activation.

Abstract: The invention relates to a method for the controlled addition of demulsifying agents (EB) to a process tank, in particular, to a separation tank (1), filled with oil and water. According to said method, an emulsion layer (E) is detected, using a sensor (2) with vertical local resolution and a sensor signal is transmitted to a feed control (3). A metered amount of demulsifying agent to be added is then supplied by said feed control (3), in conjunction with the sensor signal. This enables a minimal dosage of demulsifying agents (EB). In particular, capacitive level sensors, or gamma-ray density-profile sensors are suitable for use as sensors.
