The hard rod magnetostrictive liquid level gauge is an innovative product with high precision and reliability, effectively addressing the liquid level and interface measurement in extremely harsh operating conditions. Its measurement process is unaffected by changes in temperature, pressure, dielectric constant, and other factors due to the use of magnetostrictive technology. Its high precision, stability, and maintenance-free features effectively eliminate the shortcomings of traditional electric float switches, differential pressure transmitters, radar, and other liquid level products in field applications, thus widely used for high-precision measurements of various liquid levels and interfaces.

Product Structure:
The magnetic伸缩level gauge features a modular design, with a simple structure consisting of three parts:
Electronic Meters: Housing, Circuit Board, Electronic Module
Probe Assembly: Probe, Sensor, Magnetostrictive Wire, Buoy
Accessory Components: Buoyancy Floats and Top Flanges, etc.
Installation:
Avoid bending or damaging the level gauge probe during installation. If the probe bends, it will hinder the float's free movement along the probe, thereby affecting the measurement results. The installation steps are as follows:
1. Ensure the float size can easily fit into the buoy or mounting hole, and that the related accessories are suitable.
2. The float is directly mounted onto the probe rod of the liquid level gauge and can move freely on the rod. When installing the float, ensure that the direction marked with "UP↑" aligns with the measurement direction.
3. Clean the probe rod and float of the level gauge, removing any attachments and stains.
4. Ensure alignment at the "0" point during installation. If the ordered product requires a fixed flange, install it directly at the site. If the ordered product does not specify a fixed flange, align the "0" point during on-site installation; when the level gauge indicates 0mm liquid level, secure the level gauge to the installation flange.
5. When the process temperature exceeds 150°C, a high-temperature bracket must be installed for the top probe of the flange to ensure proper heat dissipation and reinforcement of the gauge.
6. Clean off any deposits or stains that accumulate during the surface installation of the level gauge.
