Title: Method and device for measuring the transit time of acoustic waves
Inventor: BRUST HANS-DETLEF
IPC: G10K11/36
Filed: 1988-09-30
Abstract: The acoustic waves are excited, in a frequency-modulated manner, at a point of excitation (1) on the surface of a sample (OWB) with the aid of a device for generating acoustic waves. For this purpose, a signal generator (SG) which contains a voltage-controlled frequency oscillator (VCO) with a modulation generator (RG) connected upstream, is connected to a device for generating acoustic waves. At first and second measuring points lying at a known distance from each other, the acoustic waves are detected, demodulated and evaluated in a device with a connected evaluation unit. By means of a comparison of the frequencies determined at the first and second measuring points, the transit time  tau  can be determined and then, from this, the propagation velocity of the acoustic waves between the first and second measuring points. <IMAGE>

Title: Contaminated water measurement - uses carrier gas in mixing chamber for gas sensor, to register impurities in gas
Inventor: FUHRMANN HANS DR
IPC: G01N1/34
Filed: 1991-04-09
Abstract: To measure the amt. of foreign matter in fluid, esp. water, the fluid is brought into contact with a carrier gas in a mixing chamber (16). The fluid and the gas are mixed so that the foreign matter is at least partially brought into a gas phase, and the gas mixt. is passed to a gas sensor (30) to determine foreign matter present.

The gas sensor (30) is at the upper section of the separating chamber (28), and the water flows out of the separating chamber (28) through an outlet (33) at the underside with an overflow cap (32). A heater (23) is at and pref. in the mixing chamber (16), and a thermal sensor (25) registers the temp. of the fluid leaving the mixing chamber (16). A bypass channel (34) can carry the carrier gas passing round the mixing chamber (16) directy to the gas sensor (30). USE/ADVANTAGE - For monitoring presence of hydrocarbons and halogenated carbon in the fluid, to prevent environmental damage, and also to monitor communal and industrial waste water. The technique can detect small concentrations of foreign matter in a simple operation.
