Full Description:
Purpose:
The holder is designed for professional installation of submersible hydrostatic liquid level sensors with a 28 mm body diameter, specifically the QDY30A-B model (XUYANGQIDIAN / Qidian). It is used in tanks, deep wells (up to 500 m), sumps, wastewater treatment plants, and water purification systems. The holder ensures strictly vertical positioning of the sensor, prevents cable kinking, and protects the sensor body from mechanical damage.
