Cryogenic

The Hoffer ICE Integrated Cryogenic System

The “ICE” Integrated Cryogenic Electronics incorporates the newest technological advances in electronics. Moreover, is the time-proven solutions in cryogenic flowmeter measurement.

The ICE Cryogenic System measure and records LIN, LOX, LAR, CO2, and other cryogenic liquids.

For example, truck deliveries and in-plant applications. Furthermore, the design is for cryogenic service with ease of maintenance in mind.

Hybrid Ceramic Ball Bearings Prolong Life of the Flowmeter in Fluids

The ICE Cryogenic System pairs with a Hoffer turbine flowmeter which uses hybrid ceramic ball bearings. Specifically, to prolong the life of the flowmeter in fluids that offer poor natural lubricity.

Furthermore, the system also includes a printer for delivery ticket printouts and an installation kit. Purchase individual components separately.

Many features of the ICE unit including its user-friendly interface make it a great flow computer. For instance, it features a 4.3” full-color LCD touch screen and easy-to-access panel-sealed push buttons. Specifically, this provides direct access to all measurement and configuration parameters.

Moreover, ICE’s rugged aluminum enclosure has shock mounts but can fit with an optional articulated bracket. Above, all the back panel is fitted with environmentally sealed, military-style electrical connectors for all standard and optional I/O connections.

ICE Supports Measurement of Seven Predefined Liquids

The ICE supports the measurement of “seven” predefined liquids (LIN, LOX, LAR, CO2 Single Pipe, CO2 Dual Pipe, LN2O, and LNG). Furthermore, it has “seven” selectable languages. The Hoffer ICE system carries all applicable domestic and foreign approvals for all “requiring” countries.

For example, including legal-for-trade approval in India from India Weights & Measures, MID approval for Europe, and US NTEP approval. Above, all the ICE 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 is known for its exemplary service and calibration support.

Hoffer “ICE” is the cryogenic flow computer of choice in the cryogenic industry for cryogenic tanker applications.

Hoffer Turbine meters

Hoffer has a long history of supplying cryogenic flow measurement systems on bulk delivery tankers for LIN, LOX, LAR, and CO2. Given our experience in this niche industry, it was only natural that our flow measurement solutions for tanker transports would expand to enable us to offer turbine flow meter-based flow products for use on LNG.

As a result, the flow system components we supply for tankers delivering LNG for custody transfer typically include a flanged turbine flow meter, a pressure sensor, and a temperature sensor. The most critical component we supply for LNG measurement is the ICE cryogenic flow computer.

Custody transfer flow transaction

This ICE flow computer is designed, built and calibrated by our company. Given that bulk delivery of LNG by a tanker to an end-user (customer) is a “custody transfer” flow transaction, the flow system must comply with regulatory standards appropriate for the product being sold.

For LNG transactions in the United States, the flow system must comply with Handbook 44 and NTEP approval. Additionally, ICE also meets the requirements of OIML R81 and OIML R117 with many international approvals, including MID (European Union), NMI (Australia), SIRIM/NMIM (Malaysia), NRCS (South Africa), MBIE (New Zealand), and the government of India.

LNG flow systems using the turbine flowmeter

Essentially, the principle of operation for the LNG flow systems is using the turbine flowmeter. Specifically to obtain an accurate volumetric rate of flow of the LNG being delivered. Secondly, the use of the RTD sensor to accurately measure the temperature of the LNG being delivered.

Thirdly, the pressure sensor to determine the pressure of the LNG being delivered. After that, all three signals are transmitted to the ICE cryogenic flow computer. At that point, the computer integrates the flow rate signal over time to determine the total volume of LNG delivered.

The flow computer uses the temperature and pressure signals to determine the density of the LNG in real-time against pre-loaded LNG fluid property tables. Finally, by knowing the volumetric total flow and the density of the LNG, the total mass or compensated volume of the LNG delivered can be determined within the legal requirements.

Lastly, the Hoffer ICE cryogenic flow system on LNG is available in multiple languages and supports English, Spanish, French, German, Polish, Czech, and Portuguese.

LNG Flow Measurement from Hoffer Flow Controls

Hoffer Flow Controls has been designing and manufacturing quality turbine flowmeters and related process instrumentation for more than fifty years. Our initial experience was in the field of cryogenic flow measurement. Today, our reputation in this field is synonymous with quality.

In addition, Hoffer Flow Controls manufactures high-precision turbine flowmeters to measure clean liquids and gases throughout the processing industries.
