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

Understanding Vapor Pressures
Date: 6/28/2017

Reid Vapor Pressure (RVP) is a common measure that’s typically used for assessing the volatility of hydrocarbon liquids.  To determine the RVP for any hydrocarbon liquid, the standard procedure detailed in ASTM-D323, "Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method)," should be followed.  This procedure requires heating a chilled sample to a temperature of 100 degrees Fahrenheit at atmospheric pressure using specific test equipment.  Following the standard RVP test procedure allows for the comparison of volatility across a range of hydrocarbon liquids.
Among the practical considerations related to Reid Vapor Pressure are:
  • Controlling liabilities associated with the physical loss of product;
  • Monitoring the potential for emissions;
  • Identifying requirements for safe transportation; and
  • Maximizing profit from downstream processing. 
Using methodology outlined in API MPMS (Manual of Petroleum Measurement Standards) Chapter 19.4, "Evaporative Loss Reference Information and Speciation Methodology," and results from the measured RVP of a hydrocarbon liquid, the True Vapor Pressure (TVP) can be calculated for a range of temperatures.  TVP is useful because it indicates what pressure is required to prevent flashing into the gaseous phase as a function of temperature.  TVP is also the highest vapor pressure possible for a specific hydrocarbon liquid at a given temperature.  Hydrocarbon liquids which are under pressures that are greater than their calculated TVP at any given temperature will remain in the liquid phase.  Knowing the TVP is essential for designing processes and equipment for various hydrocarbon products with different properties.
Equilibrium Vapor Pressure (EVP) is a more generalized term that describes any vapor pressure for which a liquid is in equilibrium within a closed system.  RVP and TVP can be considered as EVP for their specific conditions.  However, when dealing with transportation of hydrocarbon liquids, there are several methods that have varying conditions for temperature and vessel size that do not match the conditions specified for RVP and TVP.  As a result, it’s important to know if the vapor pressure determination conditions properly apply to its intended use.
For more guidance on the differences and uses among the various vapor pressure designations, be sure to consult with your organization’s measurement experts, whether in-house or third-party.
