Product Title
The operation is not affected by flow, foam, turbulence, floating foam, vibration, solid content, hanging material, liquid characteristics and medium changes.
Digital tube display fork frequency value, instrument self-check information, easy to test
function, timely detection of circuit damage, fork wear, material adhesion and other failures Easy to set: the most commonly used two parameters sensitivity, alarm delay can be set by a single key quickly
Long and short two kinds of tuning fork shape, wide application.
No moving parts or gaps, almost no need for routine maintenance. no need for site calibration, easy installation.
The short fork body' s " fast drop" tuning fork shape design, makes the system response faster,
suitable for viscous liquid. Multiple output modes:
Relay output
