Product Introduction
This instrument is an intelligent open channel flowmeter specially designed for the hydrological and water conservancy industry. Combining the low power consumption and multi-purpose application characteristics required by the hydrological and water conservancy industry, this instrument can not only display and output hydrological related core data, but also display and output power supply voltage, sensor working status, and other information. At the same time, the internal system not only integrates the open channel flow accumulation function of Basher groove, rectangular weir, equal width weir, and right angle triangular weir, but also supports the non weir groove mode, that is, under the standard section, the open channel flow accumulation function is achieved through the water level flow relationship calibration.
The host can directly display liquid level, instantaneous flow rate, cumulative flow rate, working status, and current voltage, with built-in EEPROM digital memory to ensure that the set parameters are not lost after a power outage. It can be widely used for measurement or monitoring of various channels, small rivers, irrigation areas, and drainage outlets, and the measurement results are not affected by water quality.
Functional characteristics
※ Support displaying and outputting air height, liquid level, instantaneous flow rate, and cumulative flow rate.
※ Support displaying and outputting the current voltage, and can remotely monitor the status of power supply.
※ Support displaying and outputting the working status of sensors, and can be remotely monitored when the sensor is disconnected.
※ Support the open channel flow accumulation function for Basher channels, rectangular weirs, equal width weirs, and right angle triangular weirs.
※ Support the non weir groove mode, which means that under standard cross-sections, the open channel flow accumulation function is achieved by calibrating the water level flow relationship.
※ Supports output through RS485 interface, standard MODBUS RTU protocol, supports modifying baud rate and device address. Communication protocols can also be customized according to needs, such as hydrological protocols, water resource protocols, etc.
