5.6.2 Transferring a File from a PC to the PT878

Once you have stored site or meter files to a PC, you can then transfer them back to the PT878 over the IR interface. The PT878 only accepts files with a

.sit (site) or .met (meter) extension. If you try renaming another type of file with a .sit or .met extension and transfer it, it will be transferred, but it will not function if you open it. Also, if you are transferring a file and the meter already has a file with the identical name, the meter will overwrite its current file with the transferred file. If the transferred file has a name longer than eight characters, the meter will shorten the name to eight characters, and replace any spaces in the name with underbars.

Note: It is not possible to download log files back to the PT878.

To download a site or meter file from a PC to a PT878:

1.Check that the Communications option on the PT878 (see page 123) 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 NT4.0, check that the QuickBeam software (available through the path C:\Program Files\QuickBeam Suite) is running.

2.You can send the file in one of two ways. For Windows NT 4.0:

•Click on the desired file, and drag it onto the rocket button in the QuickBeam window, as shown in Figure 69 below, or

Figure 69: QuickBeam Window

•Open the Send menu in the QuickBeam window, enter the Files or Files on Clipboard option, scroll to the desired file, and click Send.

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.
