Chapter 7. Logging Data

7.3.7 Printing a Log (cont.)

The PT878 shows a message indicating that its infrared sensor is looking for a printer. (If the sensor spots no printer, a window appears with this message. If it spots two printers within its range, it asks you to select the desired device.) If successful, the PT878 returns to the Log Manager, while the printer prints out the log.

7.3.8 Transferring a Log to a PC

To upload a log to a PC:

1.Check that the Communications option (see Appendix F) has been set to the IrDA protocol, and that the IR beam on the PT878 has clear access to the IR sensor connected to the PC port.

Note: For Windows NT 4.0, check that the QuickBeam software (available through the path C:\Program Files\QuickBeam Suite) is running.

2.Highlight the desired log in the left window of the Log Manager.

3.Press [MENU], scroll to the Transfer option, and press [ENTER].

The screen shows a message indicating that the PT878 is searching for an infrared device. (If the sensor spots no device, a window appears with this message, and asks if you want to try again.) If it finds a device, it sends another message indicating that it is uploading the log. (The meter also displays a message if the upload fails.) When the upload is complete, the meter returns to the Site Manager. The PC holds the transferred log in a C\Ir_Inbox folder (C:\Ir_Inbox for Windows NT, C:\My Received Files for Windows 98, or Desktop for Windows 2000). You can open the file on the PC using the PanaLog Viewer (available at www.gesensing.com) or PanaView software and export it in Microsoft Excel format.

Note: You cannot download log files back to the PT878.

PT878 specifications

The GE PT878 is a state-of-the-art portable ultrasonic flow meter designed for the precise measurement of liquid flow in various applications. As part of General Electric’s renowned instrumentation lineup, the PT878 combines innovative technology with user-friendly features, making it an invaluable tool for engineers, technicians, and plant operators.

One of the standout characteristics of the PT878 is its non-invasive measurement capability. The meter utilizes clamp-on transducer technology, allowing it to be installed on the exterior of the pipe, eliminating the need for invasive procedures which can disrupt the system or require pipe cutting. This non-contact approach not only simplifies installation but also enhances the device’s versatility, as it can be applied to a wide range of pipe sizes and materials.

The PT878 leverages advanced digital signal processing and sophisticated algorithms to provide accurate and reliable flow measurements. It operates using the time-of-flight method, whereby ultrasonic signals are sent and received through the fluid in the pipeline to determine the flow rate. This technology allows for remarkable precision, ensuring that operational efficiency can be maintained.

Moreover, the PT878 is equipped with features such as a bright, easy-to-read display, intuitive navigation, and robustness against harsh environmental conditions. Its compact and lightweight design enhances portability, making it suitable for field applications. The meter operates on battery power, providing a long-lasting solution for remote monitoring and temporary installations.

Another impressive aspect of the PT878 is its ability to measure not only water but also a variety of liquids, from hydrocarbons to chemicals. It supports multiple measurement modes, including volumetric flow and velocity, offering a level of flexibility that caters to diverse industrial needs.

In addition to flow measurement, the PT878 offers data logging capabilities, allowing users to store and analyze flow data over time. This function is vital for understanding trends, diagnosing issues, and optimizing system performance. Users can easily transfer data to computers for comprehensive analysis, enhancing operational insights.

With its combination of innovative technology, user-friendliness, and robust measurements, the GE PT878 ultrasonic flow meter stands out as a comprehensive solution for industries requiring reliable liquid flow measurement. Whether in a manufacturing plant, a water treatment facility, or any application requiring fluid monitoring, the PT878 delivers exceptional performance and accuracy.
