Endress+Hauser introduces the Proline Prosonic Flow E 100 ultrasonic flowmeter for measurement of flow, temperature and volume of process water—regardless of conductivity, pressure, density or temperature. The Prosonic Flow E 100 is ideal for use in industrial, process, power utility, fresh water, steam circuits and boiler feedwater systems.
It can measure flow in both directions as well as water temperature, making it ideal for measuring demineralized water in boiler condensate return lines, or monitoring and controlling feedwater temperature. It can also measure flow in water containing magnetite, often found in closed hot water systems for nuclear reactors, wet central heating systems and boilers.
The all-stainless-steel Prosonic Flow E 100 works in process pressures up to 363 psi, and in temperatures from 32 to 302 degrees F. It is available in line sizes from 2 to 6 inch for measuring flows up to 1680 gal/min with accuracy of ±0.5% fs. Accuracy is based on accredited calibration rigs according to ISO 17025.
The flowmeter measures volume flow rate by combining all the flow velocities determined by its sensor pairs within the cross sectional area of the meter body with extensive knowledge of fluid flow dynamics. The design of the sensors and their position ensures that only a short straight run of pipe upstream of the meter is required after typical flow obstructions, such as bends in one or two planes.
Process outputs sent via 4-20mA with HART include volume flow, mass flow, flow velocity, temperature and three totalized values. The HART signal also includes diagnostic outputs such as acceptance rate, sound velocity, signal strength, signal to noise ratio, turbulence and signal asymmetry. It also has a Pulse/frequency/switch output.
A local display has a 4-line liquid crystal display with 16 characters per line, white background lighting, and switches that turn to red in event of device errors. The format for displaying measured and status variables can be individually configured.
The Prosonic Flow E 100 also has a Web server interface. By using a standard Ethernet cable and a laptop, users have direct and complete access to all diagnostic, configuration and device data on-site—without the need for additional software or hardware. This enables targeted maintenance and service, thus saving time.
Heartbeat Technology is integrated into the flowmeter, providing self-diagnostics, extensive monitoring of the values measured, and a certified and metrologically traceable verification during operation. The operator does not need to be present in the field for most commissioning and operations activities, improving safety.
The Prosonic Flow E 100 also has the HistoROM function, which ensures maximum data safety before, during and after a service call. All calibration data and transmitter parameters are stored securely on the HistoROM data memory, and are automatically reloaded after a maintenance event.
