The HIT-4U Rate Indicator and Dual Totalizer with MODBUS communications protocol and Data Logging.
The HRT1 Rate Indicator and Totalizer with HART® communications protocol. The unit can be ordered with an optional loop powered 4-20mA output.
The CAT1 is a microprocessor controlled 2-wire 4-20mA transmitter. The CAT1 converts a low level, frequency signal from a flowmeter sensor into an analog 4-20mA output. The output is proportional to the flow rate.
The CAT2 is a versatile DC or AC powered transmitter that can be interfaced with any Hoffer flow sensor. It provides a pulse output and an analog signal proportional to the flow rate. The CAT2 can be configured with high and low alarms.
The CAT3 is a DC or AC powered, microprocessor controlled transmitter. The CAT3 outputs a pulse scaled per unit of flow, and analog signal proportional to flow rate. The CAT3 can be configured with high and low alarms.
The PET Series converter receives frequency input and converts it to a proportional 420mA or 0-10V analog output. It has been designed to fit a compact “ELBY” explosionproof enclosure. This series is designed for use with the Lo-Co Series of low cost flowmeters.
The PET Series mag-preamps are designed to convert low level sinusoidal signals into stable square wave pulses. The signal conditioners are built to fit a compact “ELBY” type explosion-proof enclosure.

Volumetric Flow Rate Indicator/Totalizer for Liquids and Gases
The Model 2000 is a volumetric flow rate indicator/totalizer that provides local display and transmits flow data for control capability. Flow rate and total may be simultaneously displayed on a two line 16 line character alphanumeric display that indicates unit of measure. English and metric units are available. Up to four flowmeter inputs can be handled simultaneously. This unit will accept pulse or analog inputs (4-20mA). Flowmeter linearization is standard on channel one and improves flowmeter linearity to ±.1% of reading when used with an HO Series flowmeter.
Mass Flow Rate Indicator/Totalizer for Liquids
The Model 2005 provides Mass flow measurement via temperature and pressure compensation . Both flow rate and total may be displayed simultaneously or independently. User may change from mass readings to volumetric readings via the front panel of the unit. Unit is programmable via the front panel. Enclosure options include panel mount, NEMA 4x and explosion-proof. The Model 2005 is a single channel unit.
Volumetric or Mass Batch Totalizer/Rate Indicator for Liquids
The Model 2007 is a batch controller that provides local display of flow rate, accumulated total and batch total. Optional temperature compensation is available for mass flow batching. This unit provides for a single flowmeter input with two stage preset capability. This feature allows the user to enter a “prewarn” value. This would be used to gradually close the valve prior to reaching the total preset value. Three analog inputs can support/display process variables.
ICE Integrated Cryogenic Electronics
The ICE ICE is Hoffer’s most advanced truck-mounted cryogenic flow metering system. ICE is a microprocessor-based totalizer designed to withstand the rigors and weather conditions imposed on truck-mounted, over-the-road cryogenic systems. Some features include: userfriendly software, preventive maintenance notification and system malfunction detection. An optional point-of-sales printed delivery ticket is available as well as a number of software options offering flexibility, customization and future expansion. The full color graphical display and electronic touch screen ensure user-friendly operator interface and provide direct access to all measurement and configuration parameters including total, rate and temperature. Designed in compliance with O.I.M.L.—R81 standard, Handbook 44 and various design approvals.
ACE II Advanced Cryogenic Electronics
ACE II incorporates technological advances in electronics and the time proven solutions in cryogenic measurements from the Hoffer ACE system. Graphical display and “soft keys” allows for 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, multi-layer 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 Hoffer Cryogenic truck-mounted cryogenic flow metering system has been designed to withstand the rigors of over-the-road service and to operate reliably in the accompanying temperature extremes they will see in actual service. Hoffer Cryogenic systems allows for superior performance and ease of use. The system provides accurate measurement of commonly delivered industrial gases while having printer output capability. The system requires minimal operator involvement.
The cryogenic system provides advanced reporting and communication capabilities including reporting for delivery, trip and maintenance via Hoffer printers or computer communication. Designed to comply with O.I.M.L.—R81 standard, Handbook 44 and various design approvals.
Hoffer offers a variety of cryogenic printers available for your Hoffer cryogenic system depending on your needs and specifications. Whether you need your printer shock mounted, water-proof or portable and lightweight, we have an option for you. Our P9 printer even offers printer capabilities in a wireless Bluetooth® design.
