Ultrasonic flow measurement, logging

The Ultrasonic Flow Measurement and Logging Family, featuring advanced DSP technology, includes two portable models, Portaflow 220 and 330, and two fixed installation models, Ultraflo 3000/4000. Both system types display instantaneous fluid flow rates or velocity and totalized values and install quickly and easily without interrupting the process stream. The systems’ data loggers can output data directly to a PC or printer or store data in the instrument’s memory for downloading at a later time.
The new instruments incorporate ‘Transit-Time’ (time of flight) DSP measurement capability, which is ideal for clean media and process liquids. These devices provide a sampling resolution of 50 pico-second and continuous single level indication to the display. Other high performance capabilities include a bi-directional velocity range of 0.33 ft/s with maximum velocity of 65 ft/s with repeatability of ±0.5% of measured value or ±0.02m/s, whichever is greater.
Instruments are supplied with two types of transducer sets to accommodate pipe sizes ranging from as small as ½” to as large as 78 inches in outside diameter(OD). Depending on model, the systems can record and store up to 98,000 (98k) or 200,000 (200k) metering points.
The flow sensors or transducers connected to the ultrasonic monitoring instrument are attached directly to the outside of the pipe being monitored, allowing for complete installation without disruption to the existing process or equipment. This is especially important to high-purity and ultra-pure applications. Since the system does not come in contact with the fluid being monitored, there is no risk of contamination to the process fluid or exposure of the monitoring equipment to corrosive or toxic liquids.
In addition to the advantages of non-invasive operation and portable or fixed installation, the new Ultrasonic Systems offer a number of other features that provide optimum functionality, flexibility, and operational convenience. These include a variable current or pulse output proportional to the detected flow rate that enables the instrument to interface with a wide range of external control devices. Unlimited pressure rating eliminates the need for different versions to handle high pressure applications and no moving parts minimize maintenance and associated costs.
GF Piping Systems’ new ultrasonic systems are suitable for a wide range of applications in such industries as water treatment/distribution, chemical processing, cooling, microelectronics, ship building, food and beverage, building services, energy management, power generation, petrochemical, oil/gas, pharmaceuticals, power plants, and manufacturing.
