Features


The FMA-4100/4300 Series flow rate can be displayed in 23 different volumetric flow or mass flow engineering units including a user specific selection. Flowmeters can be programmed remotely via RS232 or RS485 (optional). FMA-4100/4300 flowmeters support various functions including, programmable flow totalizer, high and low flow alarm, automatic zero adjustment, 2 relay outputs, jumper selectable 0 to 5 Vdc or 4 to 20 mA analog outputs, status LED diagnostic, storage of up to 10 different gas calibrations, internal or user-specific K-factors. Display models have local 2 lines x 16 characters LCD display with adjustable back light provides flow, total and diagnostic reading simultaneously. The digital RS232 or RS485 (optional) interface provides access to applicable internal data including, flow, CPU temperature, auto zero, totalizer and alarms settings, gas table, conversion factors and engineering units selection, dynamic response compensation and linearization table adjustment. The analog interface provides 0 to 5 Vdc or 4 to 20 mA (jumper selectable) outputs for flow reading.

The FMA-4100/4300 supports automatic sensor zero offset adjustment which can be activated locally via the maintenance push button or remotely via digital interface. The auto zero feature necessitates a condition of absolutely no flow through the meter during the adjustment process. Provisions are made to either start, read, or save the current auto zero value via digital commands. Digital totalizer commands include: set to zero, start at a preset flow, assign action to a preset value, start/stop totalizing and read. High and Low gas flow alarm limits can also be preprogrammed via digital interface. Alarm action can be assigned with preset delay interval (0 to 3600 seconds) to activate the contact closer (separate for high and low alarm). Latch mode control feature allows each relay to be latched on or follow the corresponding alarm status.

FMA-4100/4300 Transducers should not be used for monitoring Oxygen gas unless specifically clean and prepared for such application. See below for ordering instructions.

Rated 1 out of 5 by from Not happy with support and product received The first unit came in without the digital display I needed and I had to reorder. The second arrived without a field functional power supply. Only pigtails to plug into a power supply. Also, not what I wanted. I will rethink using your products in the future.

Rated 5 out of 5 by from Order promptness I purchased the item for a corporate buyer but he was pleased that what was ordered was what was delivered and he also commented on the quickness of the processing of the order.......

Rated 5 out of 5 by from Simple and Accurate. Install this on to measure the flow in a tube and nozzle as a testing fixture. The relays were used to set the good part to pass and were helpful. Only problem was the software was not available online and very limited. Made our own C# data acquisition software using RS232c cable and recorded values in CSV file. Also I will recommend to use LCD version, because you may need to see the live reading.

You don't have the programming software copy available online. Cannot believe 2021 still no downloadable solution available?
