Explosion-proof and anti-corrosion of diesel starch liquid online tuning fork vibration density meter transmitter
Description of Explosion-proof and anti-corrosion of diesel starch liquid online tuning fork vibration density meter transmitter
Explosion-proof and anti-corrosion of diesel starch liquid online tuning fork vibration density meter transmitter is principle of vibrating density meter with high precision, high applicability via introducing foreign advanced frequency tracking technology. Product design adopts plug-in mounting, widely used in medium density measurement in pipelines, open tank containers and closed tank containers.
Explosion-proof and anti-corrosion of diesel starch liquid online tuning fork vibration density meter transmitter is composed of two piezoelectric crystals, one piezoelectric crystal is used for generating vibration, the other piezoelectric crystal is used for measuring vibration, fork sensor built-in temperature sensor, provides temperature compensation.for piezoelectric crystal vibration.

Installation of Explosion-proof and anti-corrosion of diesel starch liquid online tuning fork vibration density meter transmitter
General installation principles:
1.The space around the bottom of the tuning fork is not less than 30 mm.The space around the tuning fork is not less than 12 mm.
2.The tuning fork body is not affected by strong currents.
3.The medium flows through the middle of the fork
4. For a more visual and systematic explanation of the installation methods, several common installation methods are specially arranged. When installing, refer to the following installation methods:
Classic installation method 1: in-line installation (low flow rate)
Classic installation method 2: oblique insertion installation (high flow rate)
Classic installation method 3: fixed installation kit installation (custom installation kit)
