UD series small-scale sewer open channel flowmeter
ULTRA SONIC WATER FLOW MONITOR
The UD series was developed as an open channel flow meter for small-scale sewers, industrial wastewater, agricultural community drainage, and tax reductions. It is a highly accurate flow meter that combines a small Permabolus Flume (PBF) with a submersible ultrasonic water level meter. Thepanel-type flow meter comes standard with a data logger, allowing you to monitor and record flow rates. Analog and pulse signals can be logged simultaneously, and data is saved to a CF card as a CSV file, allowing you to freely create reports and graphs using Excel or other programs.*High-precision flowmeter for sewer pipes Construction Technology Evaluation Regulations (former Ministry of Construction) Evaluation Product (Construction Technology Evaluation No. 88301)
Main function
- PBF flow rate is calculated from water level measurement values
- Flow rate indication and recording with data logger (panel type)
- Create daily and monthly reports using the included software (disc type)
- External output of flow analog signal and total pulse signal (rear mounting type)
