Main parameters and functions: Power supply: standard configuration 220VAC or non-standard configuration 24VDC
Difference range: 4-20mA output (programmable water level difference output current value) or optional 485, 232
Wiring: The high and low remote transducers are connected to the instrument using 4-wire connections (wire specifications only need to meet mechanical strength, recommended 4-core shielded wire, shielded single head connected to GND instrument ground, maximum transmission distance ≤ 300m). Probe selection
1. Our company will provide a dedicated ultrasonic transducer (already selected in the factory menu)
2. Menu selection, 4-20mA 321 pressure type liquid level transmitter (FM3.14YCG or FM3.14YCP). Distance measurement capability → 1, 3, 5, 7, 10, 12, 15, 17, 20 m. When the depth of the filtered water tank is greater than 10 meters, due to the emission angle, it is necessary to consider whether the width of the water tank can meet the requirements of the ultrasonic emission angle. Otherwise, please consider using a pressure type liquid level difference meter
Cold adaptation: optional (can withstand temperatures up to -40 ° without crashing)
Control output:
1. Wall mounted 3-group 6-channel relay programmable control output (3 high and 3 low)
2. Disk mounted 2 sets of 4-channel relays with programmable control outputs (2 high and 2 low)
3. Control output and linkage of water level difference
Current tracking: Differential current: 'Follow if abnormal' mode or 'Wait for abnormal' mode, menu options available
Blind spot: 0.35-1.00m → The size of the blind spot is proportional to its ranging ability, and it is inherent. The menu can be accessed
Launch full angle: 1.00mm probe protection → Ip66 accuracy → 0.25-0.5% ambient temperature → 20-+55 ℃
Display mode: Dot matrix backlight displays' high water level, low water level, water level difference 'in Chinese on the same screen. The menu can choose between backlight constant on and off modes (with delay when off), as well as instrument multi information query, etc
