Cryogenic

The Hoffer ACE II Cryogenic System

The ACE II Cryogenic System incorporates the newest technological advances in electronics and the time proven solutions in cryogenic measurement. The ACE II Cryogenic System is used to measure and record LIN, LOX, LAR, CO2 and other cryogenic liquids for truck deliveries and in-plant applications. The design is directed toward cryogenic service with ease of maintenance in mind.

The ACE II Cryogenic System is paired with a Hoffer turbine flowmeter which uses hybrid ceramic ball bearings to prolong the life of the flowmeter in fluids that offer poor natural lubricity. The system also includes a printer for delivery ticket printouts and an installation kit. Individual components may be purchased separately.

The ACE II computer offers many features including graphical display and “soft keys” allowing easy interaction between operator and the instrument. Multiple, easy to follow messages displayed in full text help the user to navigate through the instrument menu. The menu is built up hierarchically for quick access to a desired function. Electronic circuits are constructed with rugged, multilayer boards and SMT (surface mount components). The advanced computation algorithm provides multiple methods for calculating volume, mass and density of the fluid. Extensive built-in diagnostic functions allow for quick troubleshooting and identifying faulty components. Communication to external computing devices is accomplished through the RS232 serial port, and front panel infrared port. ACE II supports standard MODBUS protocol.

The ACE II Cryogenic System complies with Handbook 44 (NIST), MIL-STD 810B Shock and Vibration, NBS TN 361, ASHRAE Physical Properties of CO2, State of California Weights and Measures, and CE for Europe.

Hoffer Internals fit Daniel®'s Meters

Do you have a Daniel®’s flowmeter? Hoffer internals fit most Daniel® liquid meters and will save you both time and money. Call Hoffer or your local Hoffer representative for a cross over quote. The representative for your area may be found on www.hofferflow.com. Click on “Representatives” in the top right hand corner of the home page. Then select “Domestic Reps”. Reps are listed alphabetically.

Hoffer flowmeters are offered in 1/4” through 12” sizes for in-line meters and up to 72” for insertion style flowmeters. A 5-year warranty is available on our HO Series. Hoffer also offers a range of electronics to provide read-out , rate, total, linearization, etc.

ISA Show a Success, Call For Paper for 2005

Hoffer recently attended the ISA Show in Houston, TX at Reliant Center on October 5th-7th. The show was well attended and was reported to have had 14,500 attendees from 70 countries. The Hoffer Booth provided an increase in leads in comparison to previous years. The ISA Show provides good interaction with new and current customers as well as a meeting place for touching base with representatives, competitors, and to stay in touch with what is occurring in the flow measurement industry. Hoffer was also involved on a volunteer basis in the technical conferencing aspect at the show as well.

President, Bob Carrell, worked as a airman for (PMCD) Process Measurement and Control Division. Hoffer plans to continue next year as a volunteer to help ISA as you will read below. and high pressure versions. The unit produces a frequency pulse output. Hoffer can supply either a pulse producing preamplifier or an analog signal converter with the HP meter. The recent introduction of the HIT-1 smart signal converter allows user to take advantage of the excellent repeatability of the HP flowmeter.This means that users can achieve ±0.25% linearity over a 10:1 flow turndown range when they specify the HIT-1transmitter with the HP insertion turbine flowmeter.

Bob Carrell has recently joined the ISA Conference committee for the Field Devices-Sensing and Measurement category. The ISA Conference for 2005 will be held in Chicago, IL during October 25th-27th. To this end, Bob is issuing a call for papers, asking you to join other industry peers by presenting a paper at the upcoming ISA Show. Make your mark by presenting topics of interest and discussing the most recent advances in sensing and measurement.

Papers will be presented in sessions consisting of two or three papers per session on similar elements of the same topic. Each paper will be allocated 20 minutes and a 10 minute question and answer period. Papers must be original, concise and non-commercial. The deadline for Abstracts and Bios is March 11, 2005. The deadline for Final Papers is August 31, 2005. If you are interested in presenting please contact Bob Carrell at bcarrell@hofferflow.com or call 1-800- 628-4584. For more information on paper requirements please visit www.isa.org/speaker_resources.

Conditioners, Amplifiers, and Transmitters

Hoffer Flow Controls is pleased to present the CAT Series of flow electronics, a new compact design of flow conditioners, amplifiers, and transmitters for use in combination with Hoffer turbine flowmeters. This trio of microprocessor based devices is capable of providing signal conditioning and amplification, as well as signal transmission depending on customer needs. Several enclosure options are available including general purpose with and without DIN rail mount, NEMA explosion-proof and ATEX approved explosion-proof. CE compliant units are optionally available. The architecture of these units utilizes a combination of different circuit boards to create the many different options. Each unit is capable of holding three boards.

There are three varieties of the CAT Series. The CAT1 is an intelligent loop powered 4-20 mA transmitter with linearization, the CAT2 is a signal conditioner offering a variety of output options and also optional high and low flow rate alarms, and the CAT3 is an intelligent signal conditioner with linearization and provides a pulse output scaled per unit of flow and optional high and low flow rate alarms. For more information on this unit, contact us today at 1-800-628-4584 or visit us on the web at www.hofferflow.com.
