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

A Stable Zero Means More Reliable Measurement
Date: 2/27/2018

For many years, the natural gas industry has used transmitters to measure differential pressure (DP) in conjunction with electronic orifice meters.  Inherently, these devices may not maintain a stable zero and can transmit false readings as actual flow.  The "no-flow cutoff" setting in a flow computer can eliminate this effect by zeroing all readings below the cutoff value.
Careful consideration must be taken when setting the no-flow cutoff to avoid causing additional measurement error. False flow will be recorded if the value is set too low and real flow can inadvertently be zeroed out if it is set too high. Further, these measurement errors are magnified when combined with an oversized orifice plate.
In 2013, the API MPMS (Manual of Petroleum Measurement Standards), Chapter 21.1 ("Flow Measurement Using Electronic Flow Metering Systems – Electronic Gas Measurement"), was updated for its recommendations related to setting the no-flow cutoff.  By this standard, the cutoff value should be set to 0.25% of the DP transmitter’s calibrated range, not to exceed 0.5 inches.  However, it is crucial to also consider the relevant measurement conditions since the optimal cutoff value may vary from this recommended setting.  The measurement conditions may include: 
  • Free liquids in the meter tube;
  • Low flowing wells; and
  • Well operations with plunger lifts or intermitters. 
Regardless of the measurement conditions, a cutoff value of zero will potentially result in recorded false flow and inaccurate flow times.
While a no-flow cutoff setting can prevent errors related to transmitter-drift by zeroing readings below the cutoff value, careful consideration must be given when setting the cutoff value to prevent additional measurement error from being introduced.
Determining where to set the cutoff value can be difficult, especially since it can change over time.  Industry standards and measurement conditions should both be considered when establishing the optimal setting.  For additional information or guidance on setting your no-flow cutoff, be sure to consult with your company’s measurement experts, whether in-house or third-party.
