PCE Instruments / PCE Americas Inc.
Noise Meter / Sound Meter PCE-354 The noise meter / sound meter is a small handheld device with many functions such as peak measurement, Leq value calculation and adjustable measuring ranges. In addition, the noise meter / sound meter can freeze the largest measured value with the MAX function so that you can really judge whether a limit has been exceeded. The special feature of the noise meter / sound meter is the Leq value which, after entering a time, displays the equivalent continuous sound level, i.e. the time average...

Aichi Tokei Denki Co., Ltd.
Ultrasonic Hydrogen Gas Meters High flow measurement accuracy. Hydrogen is one of the gases through which ultrasound is least likely to propagate. As a result, the ultrasonic waves that propagate through the housing (housing noise) become relatively large compared to the ultrasonic signals that propagate through the hydrogen gas, reducing the flow measurement accuracy. We have therefore adopted a unique housing shape (patented), shown in the figure, to reduce housing noise and realize highly accurate flow measurement. 10...
