data sheet flow transmitter (flr) ultrasonic flowmeter < m-flow pw > flr, fls, fly this meter is a clamp-on type ultrasonic flowmeter for permanent use based on transit time measuring method. the m-flow pw is ideal for clean liquids containing no air bubbles such as pure water. the easy-to-use compact and lightweight design is intended for integration into mechani- cal devices. the flowmeter applicable to small and medium size pipes of diameter range from 25mm to 600mm pro - vides superior cost performance. features 1. ease of use: the detector (type: flse 2) is mountable quickly and easily. the parameters necessary for measurement can be configured on the surface of flow transmitters housing case by menu-driven software. 2. compact and light weight: the adoption of the latest electronics technology has re - duced the size and weight of the flow transmitter to one- fifth of our general use flow transmitter. 3. superior temperature effect: the adoption of sound velocity measurement system, which calculates sound velocity from transit time, keeps the flowmeter unaffected by the temperature and the pressure of the fluid to be measured. 4. quick response: with the use of fast-speed transit time processor, the system cycle is 0.2 sec that is applicable to short batch process. 5. multilingual: the following languages are supported for display: eng - lish, japanese, french, german and spanish 6. synchronization (option): simultaneous transmission to two or more converters is allowed. cross-talk between flowmeters located closely or acous - tic interference between flowmeters installed on the same pipe line can be removed by using this synchro - nization function of transmission timing of ultrasonic waves. specifications operational specifications system configuration: the system is composed of a detector (model fls) and a flow transmitter (model flr), real- izing single-path system. detector (flse12) (flse22) detector (flse41) application: clean liquids that pass ultrasound and do not contain air bubbles (such as pure water and chemical solution) turbidity: 10000deg (mg/l) or less fluid temperature (continuous use rating): -20 to +100degc (type: flse 2 3-y) 0 to +120degc (type: flse 2 3-a) -20 to +80degc (type: flse 1) with silicon rubber for acoustic couplant 0 to +60degc with silicon-free grease for acoustic couplant type of flow: well-developed turbulent or laminar flow in a full-filled pipe ( ) ( ) detector (flse31) date EDS6-123I apr. 1, 2011
