ST501 Ultrasonic Flow Meter With Insertion Transducer
▍Product Information
Flo-Instruments ST501 ultrasonic flowmeter offers high-accurate and repeatable flow measurement for liquids at an economical price. It is made of strong metal case. Combined the outstanding performance transducer with high industrial grade material, it's ideal for pipes size from 1''(25mm) up to 48''(1200mm) in diameter. Insertion transducer refers to inserting the transducer into the inside of the pipeline for flow measurement. It can accurately measure the flow rate and flow velocity inside the liquid pipeline. The advantage of the insertion transducer is that it can keep the outer surface of the pipe flat, thereby reducing pressure loss, and has high reliability and measurement accuracy.
◆ Benefits
- Measures the actual flow and total consumption ofvarious liquids
- No loss of process control, optimization of assets and efficiency, no downtime or expense from calibration.
- Adaptive signal processing algorithms optimize performance, ensuring accurate measurements even in challenging flow conditions.
- Clear display interface and LCD display with alarm function, easy to operate and debug
- Utilize transit-time ultrasonic technology so as to realize bi-directional flow measurement by precisely measuring the time it takes for ultrasonic signals to transmit upstream and downstream.
- Leverage the data logging capabilities to analyze historical flow patterns to make system optimization.
- Built-in keypad and simple menu system for fast and easy programming of pipe diameter, pipe material, liquid type, and measurement units.
