Product Introduction
The GTUM-100 ultrasonic flowmeter is an innovative clamp-on measurement device that completely eliminates the pipe cutting and processing stages, which were the biggest obstacles in conventional flowmeter installation. Equipped with a world-class ultra-precise time measurement chip, it captures and measures even extremely minute fluid flows in real time without errors at an overwhelming time resolution of up to 20ps (picoseconds).
By realizing a non-destructive measurement method where the fluid and sensor do not come into direct contact, there is no concern about internal pipe corrosion, cross-contamination, or pressure loss. It can be installed immediately while the production line is running, ensuring optimal productivity without process downtime.
This ultra-compact smart sensor is designed to precisely measure even extremely fine flow rates based on Faraday's law of electromagnetic induction. It detects the velocity of conductive liquids flowing inside the pipe and converts it into an electrical signal. Specifically engineered for ultra-small diameters (DN3 to DN32), it provides excellent stability even in low-flow environments. In particular, based on its high repeatability and durability, it delivers reliable real-time flow data even in harsh industrial processes.
Product Features
- Non-Destructive External Clamp-on Installation (Easy & Clean Setup): Simple and intuitive installation is completed just by tightening screws from the outside, without any need to cut or process the pipe.
- Zero Process Downtime (Zero Downtime & Zero Pressure Loss): It can be installed immediately while the system is running without any shutdowns, and no pressure loss or internal clogging occurs since no sensor is inserted into the pipe.
- World-Class Picosecond (ps) Accuracy: Implementing a high-performance specialized time resolution chip (up to 20ps), it delivers powerful and stable measurement reliability even in micro-flow ranges.
- Clear IPS LCD Smart Display: Adopting a high-resolution color display capable of 360-degree rotation, it allows users to identify date, signal strength, instantaneous flow, and cumulative flow data at a glance, regardless of the field installation angle.
- User-Friendly Menu Infrastructure: No need to memorize complicated menu numbers; intuitive parameter configuration and zero-point calibration are available through 4 touch keys based on a manual-guided layout.
Applications
- Semiconductor & Secondary Battery Manufacturing Equipment: Real-time micro-flow monitoring of ultrapure water and precision chemical supply lines.
- Pharmaceutical & Bio-Medical Engineering: Fluid monitoring in biotechnology processes and medical equipment where hygienic standards and cross-contamination prevention are strictly demanded.
- Food & Beverage Processing Industry: Flow totalization of product transfer lines and automated process equipment that must meet strict hygiene standard requirements.
- Precision Industrial Cleaning & Coating Equipment: Quantitative supply control of cleaning solutions, organic solvents, and alcohols or chemical solutions of various viscosities.
- Supported Pipe Specifications & Multi-Fluid Compatibility: Widely applicable to various small-diameter pipe lines, including plastic pipes (PVDF, PVC, PPR, PPH, PFA, HDPE) and metal pipes (STS, carbon steel, copper).
