XFM Smart Flow Meter with Optional Profibus Interface
Aalborg® is pleased to introduce the Model XFM, the latest addition to its programmable Thermal Mass Flow Meter line. This low cost "Smart" meter is designed for convenience (it can be programmed remotely), performance (unit stores calibration data for 1-10 gases and conversion factors for up to 32 gases), and accuracy (±1% of FS at calibration temperature and pressure).
The XFM's automatic sensor zero offset adjustment can be activated locally (maintenance push button) or remotely (via digital interface). Digital command technology starts, reads, or saves the current auto zero value.
Additional XFM Features:
Aluminum and stainless steel models.
Digital interface RS485, RS232 (with or without LCD displays), and optional Profibus DP (with I&M functionality).
Programmable Totalizer.
High/Low Flow Alarms
Self-Diagnostic Tests.
23 different Volumetric Flow or Engineering Units.
Internal or user-specific K-factors.
Aalborg®'s XFM Digital Thermal Mass Flow Meters are NIST traceably calibrated and individually programmed.

Bronkhorst High-Tech developed a field bus based pc-board for their mass flow metering and control solutions featuring self-diagnostics, alarm and counter functions, digital communication and remotely adjustable control settings. The digital "multibus" Mass Flow Meter can be equipped with on-board interface board with DeviceNet, Profibus-DP, Modbus or FLOW-BUS protocol. The newest digital Mass Flow Meters of the Select Series offer Multi Gas / Multi Range functionality featuring greater flexibility for user selection of both flow ranges and gas types, maintaining high accuracy and turndown range for measurement and control. Thanks to this feature users of the Select series can rescale their instruments on site, saving time (and money) for mounting and dismounting. For the convenience of the user, Bronkhorst High-Tech has developed a free and easy-to-use software tool called "FlowTune" for changing the configuration of Select instruments.

The latest product line developed by Teledyne Hastings Instruments is the digital version of the high capacity flow instruments. These new digital instruments allow measurement and/or control up to 10,000 slm. The new line complements the existing lower flow Digital Metaline(R) (5 sccm to 30 slm).
The two product lines, Digital Metaline and the new high capacity digital flow instruments, offer flow meters and controllers from 5 sccm to 10,000 slm, with superior accuracy. The lower flow Digital Metaline units have all-metal seals. A 4µ-inch Ra finish is available for flow rates up to 10 slm. Multiple gas calibrations and stored gas conversion factors are key features that set these instruments apart from the analog versions.
Both the Digital Metaline and the high-capacity digital flow instruments feature flexible operation with ±12, ±15 or 24 VDC power supply and transparent operation in analog or digital modes. All digital units are available with RS232 or RS485 interface with baud rates up to 19.2 kbaud. In addition, the instruments offer convenient self-diagnostics including warnings and alarms for flow, sensor, and valve status.

HIGH-TECH replacement for VA METERS
The new MASS-VIEW® flow meter series are a digital alternative to the conventional variable area meters. The new MASS-VIEW® flow meter series incorporates a digital bar graph of actual gas flow as well as indicating flow units, gas type and totalised figures.
The MASS-VIEW® series operates on the principle of direct thermal mass flow measurement. It offers a standard accuracy rating of ± 1%FS plus ± 1%RD, flow ratings from 0.2 up to 200 ln/min, and handles pressures up to 10 barg. The MASS-VIEW® incorporates the latest OLED technology, which gives a brighter readout than LCDs, can be viewed from virtually any angle and has fast signal response times. Alarm settings and the selection of a pre-installed gas or range are accessed via menu, using a 4-way navigation button on the front plate. An analog output signal enables data logging against various parameters and full accountability of gas flow.

Flow products are used in a variety of applications where liquid or gas flow needs to be monitored or controlled. In many processes, both the total quantity of product being produced and the rate at which the product is being produced must be known; flow controllers can offer that information while monitoring your process efficiency.

The Model 1030F is a microprocessor based flow rate indicator/totalizer with a 4-20 mA output that is proportional to flow rate and RS-485 communications. Flow rate and total can be displayed simultaneously on the 16-character display. The Model 1030F has five control inputs, which when switched to ground, perform specific functions such as resetting the totalizer. Four open collector control outputs may be used to interface with remote devices such as relays, counters, and lights.
