The core content of the Fuji Electric FLD-1 portable ultrasonic flow meter manual is as follows:
1. Product Overview Fuji Electric FLD-1 portable ultrasonic flow meter is a high-precision, non-contact flow measurement instrument suitable for real-time monitoring of liquid flow in industrial pipelines. Its core advantages include non-invasive measurement: there is no need to cut off the pipeline or install sensors, and it can be directly clamped on the outer wall of the pipeline for potato distribution. High precision and stability: Adopting dual channel ultrasonic technology, the measurement error is ≤± 1%, and the repeatability reaches 0.5%. Portable design: Built in rechargeable lithium battery, supporting continuous operation for more than 8 hours, suitable for rapid deployment on site. Multi parameter display: Real time display of instantaneous flow rate, cumulative flow rate, flow rate, and temperature (supported by some models).
2. Usage: Installation Preparation: Confirm the pipeline material (metal/plastic) and diameter range (DN15-DN6000), and select the matching sensor model.
. Clean the outer wall of the pipeline, remove paint, rust, or dirt, and ensure that the sensor is in full contact with the pipeline. Sensor installation clip on installation: Place the sensor perpendicular to the pipeline axis and adjust the spacing according to the "K value" indicated in the manual (usually 1/2 of the pipeline diameter). V-method installation: suitable for small diameters (DN15-DN100), sensors are installed symmetrically at a 45 ° angle. Z-method installation: Suitable for large pipe diameters or high flow rate scenarios, sensor
III. Common faults and solutions: No flow display or abnormal data. Reasons: Sensor not tightened, no fluid or low flow rate in the pipeline, signal interference.
. Solution: Reinstall the sensor and tighten it; Check the fluid condition; Stay away from sources of interference such as frequency converters. Reasons for large measurement errors: pipeline fouling, sensor aging, and incorrect parameter settings. Handling: Clean the pipeline; Replace the sensor; Check the pipeline parameter settings. Reasons for short battery life: low temperature environment, constant backlight on, battery aging. Processing: Use in an environment of 5-40 ℃; Turn off non essential backlighting; Replace the battery. Reason for communication failure: wiring error, protocol mismatch, baud rate setting error. Handling: Check the wiring; Confirm protocol type (such as Modbus RTU); Unified baud rate (default 9600bps).4. Maintenance and upkeep Daily cleaning: Wipe the sensor and host wi
