BirdDog Version 4.0

BirdDog™ Information Systems is pleased to announce the release of Version 4.0 of Remote Data Retrieval. This newest system, to which you automatically have access when you log into our host site, provides enhanced features that are certain to make you even more productive... such as a more streamlined and intuitive user interface, the ability for end-users to perform ad hoc changes to alarm settings, and layered administration. With layered administration, end-user organizations can assign BirdDog client administrators who, in turn, will be able to add/delete other enterprise users, set each user's rights (from read-only through full editing, including use of Demand Polling), reset user passwords, add/delete Morning Report recipients, and much more.

In addition to the BirdDog Remote Data Retrieval system functional enhancements, we've also deployed new security provisions to further complement our previously implemented use of an HTTPS website to provide full SSL encryption of your sensitive and proprietary information. These enhancements include the use of unique email addresses as User IDs, as well as stronger Password requirements with history restrictions and forced routine changes. As before, with just a single account User ID and Password, your log-in will provide direct access to all BirdDog SaaS (Software-as-a-Service) systems to which you have end-user rights. And as you add or remove systems from your user profile, the single sign-on process will automatically recognize those changes.

BirdDog Security Policy Change Alert

Security Policy Change Alert - For the enhanced security of BirdDog™ Information Systems users, effective November 11, 2013, User IDs will be unique email addresses and account password requirements will be strengthened. New passwords will need to be at least 8 characters in length and contain at least one each of the following characters: uppercase alphabetical; lowercase alphabetical; numeric; and “special” (such as @, &, _, #, etc.). At the appropriate time, you will be prompted during your BirdDog log-in to click on a webpage link that will provide more details and guide you through your password change process.

BirdDog System Support

  • Log-in and system support, including password resets, are available to customers on a 24x7 basis by calling, toll-free, 800-231-9741. During business hours (8:00 a.m. until 5:00 p.m. Central Time, Monday through Friday), your call will be directed to the appropriate technical support or customer service team member.

  • During non-business hours, callers will be presented with a main menu which includes an option to reach system support and, if appropriate, to mark your message as “urgent” for an expedited response. Non-urgent support calls will be returned the next business day.

  • System support requests or questions may also be submitted via e-mail to

Effects of Installing an Orifice Plate Backwards
Date: 10/26/2017

The orifice meter is the device most commonly used for measurement of natural gas in the upstream sector of the oil and gas industry.  While there are several vital components to an orifice meter, the orifice plate is perhaps the most crucial.
The orifice plate, as defined by AGA Report No. 3, "Orifice Metering of Natural Gas," is a thin metal plate with a machined circular and concentric bore, a sharp edge on the upstream side, and a beveled edge on the downstream side.  Orifice plates are beveled on the downstream side to help minimize the plate’s contact with the flowing gas stream passing through the meter.
At first glance, it’s not uncommon for those new to orifice measurement to assume that the beveled edge should be the upstream side of the orifice plate.  However, installing a plate with the bevel pointing upstream into the flow (i.e., a "backwards plate") can create significant error in the flow rate calculation resulting in understated volumes.  The amount of beveling required on plates of the same thickness decreases as the meter tube inside diameter (ID) increases.  Therefore, plates installed backwards in larger tubes (e.g., 6" ID and above) may introduce less inaccuracy than plates installed in smaller tubes (e.g., 4" ID and below).  Since the bevel creates a reduced differential pressure across the plate when installed backwards, the measurement technician must be careful to correctly install the orifice plate to obtain differential readings which are accurately proportional to the flow.  Otherwise, substantial flow error may be introduced which could cause the flow rate, in many cases, to be understated by 15% or more.
One of the best ways to confirm proper installation of an orifice plate is to review the flowing parameters and flow rates measured before and after the meter inspection or plate change.  Assuming consistent operations prior to and after installation of the orifice plate, any significant changes in these values should be reconciled.  Whenever possible, the measurement technician should verify that the orifice plate was installed correctly before leaving the site since any errors could potentially go unnoticed until the next inspection.  Careful installation and maintenance, as well as accurate, detailed, and comprehensive reporting, are the most useful practices for preventing the backwards installation of an orifice plate.
For more guidance on orifice meter design, installation, calibration, inspection, and, of course, proper installation of orifice plates, be sure to consult with your in-house or third-party measurement experts.
