Selecting the Right Dayu Electronics Explosion-Proof Ultrasonic Level Meter: Key Points You Can't Miss

When selecting the appropriate explosion-proof ultrasonic level meter model, multiple factors need to be considered. Here are some key steps and points to help you make an informed choice:

Define measurement requirements:

Identify the type of medium to be measured (such as clean water, sewage, diesel, crude oil, etc.) and its characteristics (such as the presence of vapor, mist, foam, etc.).

Specify the measurement range (e.g., 5m, 10m, 15m, etc.) and the required blind zone size (typically between 0.25m and 0.6m).

Consider the working environment:

Understand the temperature range of the working environment (e.g., -20°C to +60°C) to determine if the level meter can operate properly.

Pay attention to working pressure and corrosiveness, especially for the medium inside tanks; know the tank material and whether there is an anti-corrosion lining.

Explosion-proof and anti-corrosion requirements:

Based on the explosion-proof requirements of the application environment, select equipment with appropriate explosion-proof and sealing ratings.

If the medium is corrosive, choose probes and housing materials with anti-corrosion properties (such as PVDF).

Technical parameters:

Accuracy: Choose the appropriate accuracy based on measurement needs, typically between 0.25% and 0.5%.

Resolution: Ensure the resolution of the selected device meets measurement requirements; common resolution is 1mm.

Output signal: Select 4-20mA current, RS485/Modbus protocol, or other communication outputs based on system requirements.

Installation and maintenance:

Consider the installation method of the instrument (e.g., bracket mounting, flange or nut fastening, etc.) and wiring method (two-wire or four-wire).

Understand the calibration method and parameter settings of the instrument, as well as after-sales support.

Special environment considerations:

If used in extreme temperatures, lightning-prone areas, or environments with corrosive gases, choose equipment with corresponding protective measures, and possibly install additional lightning protection devices.

If the medium has stirring, waves, or foam, select equipment with appropriate handling capabilities or consult the technical service department.

Comprehensive evaluation:

When selecting a explosion-proof ultrasonic level meter model, comprehensively consider factors such as measurement requirements, working environment, technical parameters, and installation/maintenance, and choose the equipment that best suits your needs.

Refer to the technical parameters and performance indicators of explosion-proof ultrasonic level meters from different brands and models, and conduct comparative analysis to make a more informed decision.
