Description Tuning Fork Density Meter
Tuning fork density meter is the introduction of foreign advanced
frequency tracking technology and the production of high-precision,
high applicability vibration principle density meter, product
design using plug-in installation, widely used in pipelines, open
tank containers and closed tank containers In the medium density
testing.
Tuning fork density meter sensor is composed of two piezoelectric
crystals, one piezoelectric vibration, the other piezoelectric
crystal vibration detection, tuning fork sensor built-in
temperature sensor, the piezoelectric crystal vibration temperature
compensation.

The internal circuit board with automatic filtering function, other
vibrations like pipe vibrations can eliminate away from the side of
circuit and software,which ensure accuracy.
Feature Tuning Fork Density Meter
1.Adopting Germany piezoelectric ceramic piece, crossing gold
process for ceramic piece to increase the inoxidizability of
ceramic piece, thus increasing the service life of densitometer.
2.Fork vibration original piece adopts Japan's high performance
original piece, in which installed 24 AD converter, and the
accurate recognition for frequency is 0.01HZ, to ensure the
sensitivity and accuracy of density.
3.Fork density calibration adopts national density standard
solution, to ensure the source and accurate of density.
4.The current circuit is independent of fork vibration circuit,
there is isolating anti-interference inner, reducing the influence
to instrument from disturb.
5.There is set density three point quick calibration, range adjust,
current calibration etc function, to meet on-site working demands.
6.Using high precision measuring density, is mainly used in power
plant.
7.Can not be affected by temperature, pressure and flow rate , the
factor affecting measuring error Is less.
