ST502 Ultrasonic Flowmeter With RS485

ST502 Clamp-on Ultrasonic Flowmeter

Ultrasonic flow meters that use transit-time methods to measure flow.


Introduction

ST502 Ultrasonic flow meter use the most reliable digital signal processing technology, transmitting flow measurement for a wide range of liquid and pipe size with high accuracy and reliability. Combined the outstanding performance transducer with higher industrial level material, Flo-Instruments could have long time work without any worries.


Clear menu display selections make using instruments very convenient. Clamp-on transducers makes the unit more flexible over a wide range of applications.


Operating and maintenance cost of flow metering can be significantly reduces by Flo-Instruments ultrasonic flow meter. Operating cost are flow because there is no need to break the pipe. Additional maintenance is seldom if there is no wear.
