D118 Ultransonic Flow Meter

Ultrasonic Flowmeter D118· Achieve high accuracy at low and high flows· Simply clamp-on outside of pipe for easy set up· Save time with no pipe cutting or process shutdownOverviewUltrasonic flowmeter D118 is a high-performance general purpose clamp-on flow meter incorporating the latest developments in universal transit-time digital signal processing to offer excellent accuracy and repeatability for a wide variety of liquids. The flow meter measures the time it takes an ultrasonic signal to travel a known distance with the flow stream and another signal travelling against the flow stream, determining the velocity of the fluid being measured.Ultrasonic flowmeter D118 clamp-on meter can also be ordered with insertion transducers to eliminate problems with pipe wall thickness, liners, wall deposits, and where difficult piping configurations present signal strength issues.Common applications include: · Cooling and heating fluid measurements· Water and wastewater measurements· Leak detection in piping systems· Monitoring and controlling of HVAC systems· Fuel and oil consumption measurements· Contactless product recognition· Interface detection· Offshore applications· Automated process controlProduct Benefits· Designed for liquid flow metering applications· Tolerant of liquids with small amounts of air bubbles or suspended solids· Clamp-on version is standard, insertion transducers available· No moving parts to clog or fatigue like turbine meters· Transducers clamped to outside of pipe· Permanent or temporary installations· Immune to the process compatibility concerns· Install meter during plant operations· No process shut-downs, no leakage risks· Operational safety and robustness· Ideal for large line sizes or exotic materials· Low maintenance, no moving parts, robust construction· High zero stability, nearly drift free· Mounting kit included to lock transducer into place· Modular electronics enabling field upgrades· SD card data logging capability· Large display with push buttons, user-friendly menuSpecifications· Accuracy: +/- 0.5% of reading from 0.03 ft/s to 40 ft/s ( 0.01 m/s to 12 m/s)· Repeatability +/- 0.15% of reading· Wide turndown ratio· Bi-directional flow range of 0.03 to 40 ft/s (0.01 to 12 m/s)· Pipe sizes from 2 to 236 inches (50 to 6000 mm)· Process pipe-wall temperature:  -40°F to 176°F (-40°C to 80°C)· Insertion transducers available: 1.5 inch (38.1 mm)· 1GB SD card high memory data logger· Temperature:  Ambient: -40°F to 140°F (-40°C to 60°C)  Operating: -40°F to 176°F (-40°C to 80°C)· Power supply options:  90 to 250 VAC, 48 to 63 Hz  10 to 36 VDC at 1A· Output signals:  4 to 20 mA     Pulse (configurable)  Relay (configurable)· Digital communications: RS-232, RS-485, Modbus RTU· Materials:  Enclosure NEMA 4X (IP65), die-cast aluminum  Transducers IP67 (Encapsulated)· Standard cable length: 30 ft (9 m), Maximum cable length: 300 ft (90 m)
