Description
Wall-Mounted ST505 Ultrasonic Flow Meter
Equipped with industrial-grade materials and transducers for durable long-term flow measurement
Product Overview
ST505 Stationary Ultrasonic Flowmeter - Integrate into your management system to provide remote measurement services.
The ST505 ultrasonic flow meter uses reliable digital signal processing technology, transmitting flow measurement for a wide range of liquids and pipe sizes with high accuracy and reliability. Combined with outstanding performance transducers and higher industrial-level materials, Flo-Instruments ensures long-term operation without concerns.
Clear menu display selections make instrument use very convenient. Clamp-on transducers provide flexibility across a wide range of applications.
Based on Transit-Time technology, the ST505 offers high measurement accuracy. Using clamp-on transducers, it collects flow data by clamping onto the outside of the pipe, never contacting the fluid, preventing liquid pollution, pressure reduction, or leakage.
Key Benefits
  • Measures actual flow and total consumption of various 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
  • Utilizes transit-time ultrasonic technology for bidirectional flow measurement by precisely measuring ultrasonic signal travel time
  • Leverage data logging capabilities to analyze historical flow patterns for system optimization
  • Built-in keypad and simple menu system for fast programming of pipe diameter, pipe material, liquid type, and measurement units

Installation Methods
V Method
The "V" method is considered the standard method. It usually provides more accurate readings and is used on pipe diameters ranging from 25mm to 400mm (1" ~ 16") approximately. It's convenient to use but requires proper transducer installation, contact on the pipe's centerline, and equal spacing on either side of the centerline.

Z Method
The signal transmitted in a "Z" method installation has less attenuation than with the "V" method because it utilizes a directly transmitted signal that transverses the liquid only once. The "Z" method can measure pipe diameters ranging from 100mm to 3000mm (4"~120").
ST505 Wall-Mounted Ultrasonic Flow Meter with ±1.0% Accuracy, Transit-Time Technology, and Clamp-On Transducer
N Method
With the "N" method, sound waves transverse the fluid twice and bounce three times off the pipe walls. It's suitable for small pipe diameter measurement. Measurement accuracy can be improved by extending the transit distance with this method (uncommonly used).

W Method
Similar to the "N" method, measurement accuracy can be improved by extending the transit distance with the "W" method. Sound waves transverse the fluid four times and bounce four times off the pipe walls. It's suitable for very small pipes (diameter less than 50mm/2").
