The FMA-2600A Series mass and volumetric flow controllers use the principle of differential pressure within a laminar flow field to determine and control mass flow rate. A laminar flow element (LFE) inside the meter forces the gas into laminar (streamlined) flow. Inside this region, the Poiseuille equation dictates that the volumetric flow rate be linearly related to the pressure drop. A differential pressure sensor is used to measure the pressure drop along a fixed distance of the LFE. This, along with the viscosity of the gas, is used to accurately determine the volumetric flow rate. Separate absolute temperature and pressure sensors are incorporated and correct the volumetric flow rate to a set of standard conditions. This standardized flow rate is commonly called the mass flow rate and is reported in units such as standard cubic feet per minute (SCFM) or standard liters per minute (SLM).

The controller uses a true proportional valve coupled to the flow body to control flow using the integral PID loop controller. Standard units include a 0 to 5 V output (4 to 20 mA optional) and RS232 communications. The gas-select feature and the setpoints can be adjusted from the front keypad or via RS232 communications. Volumetric flow, mass flow, absolute pressure, and temperature can all be viewed or recorded through the RS232 connection. It is also possible to multi-drop up to 26 units on the same serial connection to a distance of 46 m (150').

Is there another version on serial communication protocol for the FMA-2600 series that does not involve the HyperTerminal?

Asked by: shep25
Thank you for your inquiry! Unfortunately, we do not offer any software with these units and with HyperTerminal not being included in newer Windows versions another program will be needed. Putty may be used as an alternate if HyperTerminal is not available

Do you have the distance from the center of the gas inlet hole to the edge of the device? I can attach a diagram showing which dimensions I need if there is a way to do that

Asked by: AGCQ
Thank you for your inquiry about the mass flow meter. Please forward that picture or drawing to flow@omega.com for the distance you described.
