Ultrasonic Flow Transmitters suit water supply systems.

Press Release Summary:

Providing continuous 4-20 mA flow signal, Model CSLFC transmitters measure flow in municipal/private water supply systems in ranges from 15-700 gpm in ¾-10 in. pipe. Manufactured of Schedule 40 carbon steel, units feature ULTEM® encapsulated ultrasonic transducers and epoxy-coated pipe body material. Their mixed-signal ASIC has algorithm that calculates velocity of flow and ultimately volumetric flow rate. Output is unaffected by water temperature, density, and viscosity changes.

New Flow Transmitters Ideal for Municipal Water Systems and Green Technology Applications

Clark Solutions CSLFC Ultrasonic Flow Transmitters are ideal for measuring flow in municipal and private water supply systems. All Clark Ultrasonic Flow Transmitters feature excellent long-term stability, no pressure drop, and no moving parts making them very reliable. These flow transmitters are easy to install and can fit into tight installations where other meters cannot.

Hudson, MA - Clark Solutions announces the availability of a new line of ultrasonic flow transmitters ideally suited for use in private and municipal water supply systems. These transmitters are ideal for measuring flow ranges from 15 to 700 GPM in ¾" to 10" pipe. Like all Clark Ultrasonic Flow Transmitters, Model CSLFC Transmitters feature no moving parts, excellent long-term stability, no pressure drop, and high accuracy at a lower cost than similar instruments. Built out of Schedule 40 carbon steel, CSLFC Transmitters feature ULTEM® encapsulated ultrasonic transducers with a choice of EPDM, Buna-N, Neoprene(TM), FKM, or other seals, and epoxy coated pipe body material. Clark Ultrasonic Flow Transmitter Model CSLFC provides a continuous 4-20mA flow signal. Available options include direction of flow capability, NEMA 4 and 8 pin connector receptacles for simplified installation, and a DP/DS Panel Meter/Display. Model CSLFC Transmitters are available for purchase online at www.clarksol.com/html/cslfc.cfm

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 Flow 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 water 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.
