Accurate, Economical Ultrasonic Flow Meter -Image

Hudson, MA – The CSLFB Ultrasonic Flow Meter,  part of the Clark Sonic family of ultrasonic products ( is designed for high accuracy flow measurement and features a proprietary mixed signal ASIC which provides sophisticated timing and control. 

CSLFB ultrasonic flow meters are unaffected by changes in fluid temperature, density, or viscosity and have no moving parts in the flow path.  CSLFB Ultrasonic Flow Meters have negligible pressure drop and are better suited for monitoring media containing entrained solids than other flow monitoring devices.  In addition, CSLFB Ultrasonic Flow Meters are easy to install and substantially less expensive and more accurate than typical “strap on” type ultrasonic meters.

CSLFB Ultrasonic Flow Transmitters are bi-directional, rated for flow ranges to 120 GPM, and are available in 3/4" to 2" pipe sizes. Maximum working pressure for CSLFB Ultrasonic Flow Transmitters is 250 PSI (17.2 bars) for fluids having temperatures of -4 to 190°F (-20 to 87.8°C).  An optional 3-wire RTD, 100 Ohm, Platinum, Class A, IEC60751 temperature sensor is available for temperature and energy monitoring applications.  All CSLFB Ultrasonic Flow Transmitters have 4-20 mA output as standard; a second output is available in the form of an optically isolated NPN transistor, configured at the factory.  Wetted materials include ULTEM® encapsulated ultrasonic transducers with a choice of elastomer seals and brass body material.

Available for purchase online at, CSLFB ultrasonic transmitters are economically priced starting at $688.
