Operating Precautions

1. Installation Requirements

Install the instrument on horizontal straight pipeline; keep sufficient straight pipe length before and after the meter. Avoid installation at pump outlets, elbows and turbulent flow sections to prevent unstable detection data. Clean pipeline internal gravel, sundries and large solid blocks before mounting.

2. Commissioning Rules

Complete water zero calibration after installation. Set upper and lower concentration limit parameters matching on-site mortar property to realize automatic linkage with delivery pump and dosing equipment.

3. Normal Running Management

Prohibit long-time empty pipe operation without medium, which may damage the tuning fork probe and cause abnormal readings. Avoid abrupt sharp surge of pipeline flow pressure during continuous production. Check real-time display and PLC feedback data per shift.

4. Periodic Maintenance

Clean silt, sand and bonded mortar on the fork surface every 15~20 days. Perform sampling comparison and instrument calibration monthly to ensure measuring accuracy. Regularly inspect flange sealing and connecting cable integrity.
