Ultrasonic Flow Transmitters suit Green applications.
January 19, 2009 -
Featuring brass construction, CSLFB Ultrasonic Flow Transmitters offer full-scale flow ranges from 15-400 gpm in ¾-3 in. pipe, with accuracy of ±0.75%. Devices are based on mixed signal ASIC, which combines timing, control, and transducer drive circuitry. Units measure flow rates of acoustically conductive liquids, including most clean liquids and many liquids with entrained solids. Output is unaffected by changes in fluid temperature, density, and viscosity.
Clark Ultrasonic Flow Transmitters Ideal for Green Technology Applications
Clark Solutions CSLFB Ultrasonic Flow Transmitters are ideal for measuring flow in most clean liquids and many liquids with entrained solids. Applications include monitoring flow rates of chilled or heated water as part of a green technology program as well as in municipal, process, and industrial systems. Clark CSLFB Ultrasonic Flow Transmitters free users from having to calibrate the transmitter to fluid temperature, viscosity, or density making them very easy to deploy and very reliable.
Hudson, MA - Clark Solutions-a leading manufacturer and distributor of pumps, valves, and flow instrumentation introduces its CSLFB Ultrasonic Flow Transmitters. These transmitters are ideal for measuring flow rates of acoustically conductive liquids, including most clean liquids and many liquids with entrained solids. Model CSLFB Ultrasonic Flow Transmitters are designed for full-scale flow ranges from 15 to 400 GPM in ¾" to 3" pipe. They are a rugged cast brass design and have an accuracy of ±0.75% F.S.
Available for purchase online at http://www.clarksol.com/html/cslfb.cfm , these transmitters feature no moving parts, excellent long-term stability, no pressure drop, broad fluid compatibility, and high accuracy at approximately half the cost of similar instruments.
At the heart of the Clark Ultrasonic Flow Transmitter is a proprietary mixed signal ASIC, (Application Specific IC,) which allows sophisticated timing, control and transducer drive circuitry to be combined on a single integrated circuit. The ASIC uses a special algorithm that is an improvement upon the standard single-path measurement technique. Clark Ultrasonic transmitters utilize the "sing around" method, where the ultrasonic transducer alternates between transmitting and receiving to measure differences in flight time between upstream and downstream transmissions. The flight time of the sound pulse from the transmitting transducer to the receiving transducer will be shortened if the pulse is launched in the direction of flow, and increased if launched opposite to the direction of flow. By alternating the transmitting and receiving transducers, the difference in these transit times can be used to calculate the velocity of the flow, which when multiplied by the area of the pipe results in a measure of volumetric flow rate. The primary advantage of the Sing Around method is that the velocity of the fluid is being measured independent of the relative speed of sound in that given fluid. The output of Clark transmitters is also unaffected by changes in fluid temperature, density and viscosity.
Clark Solutions has a fifty-year history of providing unique solutions to the measurement, control, and monitoring of pressure, flow, and level in liquids and gases. Located in Hudson, Massachusetts, the company offers instrumentation, valves, and pumps to record, monitor, and control flow, velocity, pressure, temperature, humidity, level, gas concentration, and other properties.
