Sound and light alarm
Liquid level display device WH311
Water replenishment solenoid valve (refer to the water supply and drainage discipline for details)
Other system descriptions: The fire control room is equipped with two sets of liquid level display devices. Liquid level detectors are added to the basement fire pool and roof fire water tank to display the overflow level, maximum level (alarm), air conditioning level, fire level, below normal fire level (alarm), and minimum effective level (alarm) in the fire pool; Display the overflow water level, the highest water level (alarm), the fire water level (close the electric valve of the inlet pipe), the lower than normal fire water level (alarm), the intermediate water level (open the electric valve of the inlet pipe), and the lowest effective water level in the fire water tank
The WH311 water level display instrument can effectively solve the problem of remote measurement of liquid level and help digital monitoring of building safety. Accuracy: 0.1%FS, 0.25%FS Certification information: CE, FCC, RoHS rated range: 0~30cm~0~200m Output signal: 2-wire system 4~20mA
