Case Description

The requirement is to transform the display of the fire water tank in the control room into an electronic automatic water replenishment system, and to display the water level changes in real time in the control room. It requires that water replenishment starts at 3.5 meters and stops at 5 meters.

I. Needs Analysis

Realizing intelligent control of automatic water replenishment is an important application of the WH311 intelligent level controller. It mainly uses the relay switch output signal of the high and low level alarm of the display and the hysteresis value setting to control.

II. Scheme Design

Wiring Instructions:
1. Place the WH311 level probe directly at the bottom of the fire water pool or fire water tank.
2. Connect the WH311 level probe and the secondary instrument WH6 in the fire control room through a cable.
The control room provides a 220V power supply.
The power module of the display will automatically supply power to the WH311 level probe.
The real-time current water level height is displayed on the screen.
Set the upper limit alarm value AH to "5 meters".
Set the hysteresis value to "1.5 meters" using the SET button to "HYA1" (start at 3.5 meters and stop at 5 meters. This value can be set by the user according to process requirements).
