1.Integrated structure design (accumulator, liquid level sensor is one), which reduces the operation difficulty of field staff.
2.Ultrasonic non-contact liquid level measurement, which has no effect on the flow rate, is an ideal liquid level meter.
3.The probe has the advantages of low power consumption, simple installation and easy positioning. It is widely used in rivers, water supply, factories, urban sewerage and other related fields.
4.The type of suitable water Weir groove is wide, including thin-wall right-angle triangular Weir, rectangular Weir, Barschel Groove, etc.
5.The voltage adapts to a wide range and can work within a DC voltage of 12-24V.
6.Support for custom serial port data format
7.Support for three and four wire current output mode
8.Optional built-in GPRS module, radio module, Bluetooth module
9.Menu Interface in Chinese and English on OLED display screen
10.3-channel limit NPN collector open circuit control output setting, for material level, liquid level control
11.2 circuit relay control output setting, for material level, liquid level control
12.4~20mA current output, RS485 serial data output or 0 ≤ 5V voltage analog output optional
13.Wireless transmission mode: radio, GPRS, Bluetooth
14.Select PC serial port output and conversion accessories, can be directly with the PC network.

II.Technical parameter
（1）Cumulative flow range:0-9999999 (full 8-bit clear, simultaneous accumulation times plus 1, flow unit according to setting)
（2）Instantaneous flow range: 10L/s~100m3/s (determined by the type and specification of the measuring Weir trough)
（3）Flow accuracy:<5%, <3%(order selection).
