1. What is the square of the signal line of the nine wave flowmeter?

Continuous power supply (external power supply). The 4-20mA signal of the ultrasonic flowmeter is instantaneous. If you have to set the output response, please choose 1ms. Battery powered is noisy for 30s.

2. The nine wave flowmeter has records but does not display data.

If the nine wave flowmeter has records but does not display data, it is usually due to a fault in the sensor signal processing link or display unit. It is necessary to check the signal transmission link and display module power supply. 1. Problem diagnosis steps: ① Signal transmission inspection • Check whether the wiring between the sensor and the display instrument is loose or corroded, with a focus on whether the shielding wire grounding is reliable • Use a multimeter to measure the voltage/current value of the signal output terminal: 4-20mA output corresponds to 4mA (0 flow) and 20mA (full range) standards, and pulse output needs to be detected with a frequency meter • If the signal is normal but not displayed, the fault point is in the display unit ② Display unit detection • Confirm the power supply voltage of the display screen (usually 24VDC ± 10%), and if it is lower than 21V, it may trigger undervoltage protection • Check whether the mainboard fuse (usually 0.5A-1A) is blown • Try to restore the factory settings: simultaneously press and hold the "SET"+">" keys for 10 seconds (specific combination needs to refer to the model manual). 2. The sentence is: Common causes of malfunctions • Sensor probe scaling leading to signal attenuat

ion (commonly seen in sewage measurement) • Main board AD conversion module damaged base combustion dust (requiring factory repair) • Display backlight malfunction (weak data visible under strong light oblique view) • Parameter setting error (such as range set to 0) 3 Emergency response plan • Activate the backup recorder interface (RS485/MODBUS) to export data • Short circuit signal input terminal analog signal test (4mA corresponds to 0%, 12mA corresponds to 50%) • Replace the backup display head (pay attention to protocol matching). In high-voltage or explosion-proof situations, section cleaning must be operated by certified personnel, and non professionals are strictly prohibited from disassembling explosion-proof shells.

3. What should I do if there is no signal for the calibration and echo of the Beijing Jiubo open channel flowmeter?

1. Firstly, there is a fault in the open face of the square source rock connecting the cable (excitation circuit, signal circuit) system. Check whether the cables connecting the excitation system and signal system are connected and correctly connected.

2、 Secondly, power supply failures such as not being connected. Firstly, confirm that the power supply has been connected, and then check all parts of the power supply. Check the main power supply and excitation current fuse during the hail season. If the current meets the specified value and the new fuse is reconnected but melts, the fault location must be identified. Check if the output voltages of the power circuit board are normal, or replace the entire power circuit board.
