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.

Natural Gas Measurement Basics: Gauge-Line Error from Pulsation
Date: 7/27/2011

Natural Gas Measurement Basics: Gauge-Line Error from Pulsation
Common industry practice is to install gauge lines (meter tubing) of less than 18 inches between the tap valves and differential pressure transmitter on an orifice meter. This minimizes the potential for multiple sources of measurement error including meter freeze, liquids, and, perhaps even more importantly, gauge-line error due to pulsation.

Gauge-line error associated with compressor-generated pulsation occurs when a quarter-wave resonance occurs in the meter tubing. According to well respected and widely accepted studies, most pulsation present in orifice meters has wave lengths longer than 72 inches. Therefore, if the gauge lines are less than 18 inches
(one-quarter of 72), the likelihood of gauge-line error should be effectively eliminated.

You may click here for basic field procedures to detect the presence of gauge-line error. Please note that this is not a method to detect measurement inaccuracies associated with square-root error, which always causes an orifice meter to read high and can be very difficult to detect. For a more comprehensive review of the methods to detect and eliminate errors associated with compressor-generated pulsation, you're invited to register for one of our Lunch & Learn classes scheduled during the remainder of 2011. The full schedule is available on our website at, along with a registration form in PDF format, or you may contact our offices at 800-231-9741 for more details.
