The Vibration Meter with Piezoelectric Accelerometer (Speed) has been manufactured with patented technologies and is equipped with more functions and advanced performance than previous versions. The new version retains most of the excellent features and functions of the previous versions. Functions include the pulse measurement technology, the ultrasonic igniting and the small signal receiving of circuits.

The main improvements are made on the battery supply circuit and on the transmitting circuits. All other circuits are simply integrated into this new version without major modifications. The Vibration Meter with Piezoelectric Accelerometer (Speed) has been upgraded to surpass previous models.

The hardware features simple operation use, high accuracy and outstanding reliability, while the software provides a very user friendly interface with many functions. The flow meter employs the patented balanced lower voltage multi-pulse igniting circuit which increases the anti-interference ability magnificently, so that the flow meter will work in demanding industrial environments such as those with power frequency transverses nearby.

How To Use

Indicators on the display make it simple to know when you are receiving reliable results:

  • When ‘R’ is displayed in the lowest right corner of the LCD display, the instrument is working properly.
  • If an ‘H’ flashes on display, there could be poor signal received.
  • If an ‘I’ is displayed, it means that there is no signal detected.
