The FM-200 Series is a bi-directional digital flow sensor for use with air or Nitrogen gas. It offers high precision detection in an ultra small package, thanks to the utilization of MEMS technology. The series covers a wide range of flow rates and has a wide range of I/O options standard, such as dual discrete outputs, an analog voltage output, and an external input. Dual digital display: The integrated two-color dual digital display offers quick and easy verification of the sensor's operation, including flow rate, direction, and output condition. Bi-Directional flow detection: The unique sensor chip of the FM-200 allows for flow sensing in both directions. The unit utilizes two temperature sensors, one on each side of a heater element, to determine the heat distribution. This concept provides accurate detection, regardless of flow direction..
The sensor features a dual color digital display, which allows operators to check the status of the sensor operations at a glance
The sensor features a new rectification mechanism, as well as a Micro Electro Mechanical System (MEMS) technology, which allow the sensor to be mounted on a Si sensor chip (3 x 3.5 mm) and provides an extremely small heat capacity, high precision of ±3% F.S., and high-speed response. The two temperature sensors on either side of the heater detect heat distribution and enable bidirectional detection.
A single sensor can detect flows in two directions, making it suitable for a variety of applications
The sensor features a new rectification method which eliminates the need for straight pipes at both the intake and exhaust sides.
The cover-attached connector enables quick connection.
There are no limits on installation, other than the ability to carryy out bidirectional detection.
The FM-200 series is capable of controlling and managing flows in wide variety of output modes, depending on the required application.
When the volume of flow of the gas being measured reaches a set integrated value, output switches ON or OFF.
Integrated pulse output mode
The pulse output is generated once at every specified integrated value, allowing the operator to know the amount of air consumed per unit of time with ease.
Energy-saving and environmentally friendly
The pulse output from the flow sensor can be inputted to the pulse counter of an Eco-Power Meter so that air consumption and power consumption can both be measured simultaneously.
Window comparator modeThis mode is used for setting comparative output to ON or OFF at flow rates within the setting range.
Hysteresis modeThis mode is used for setting comparative output hysteresis to the desired level and for carrying out ON / OFF control.
Output OFF modeComparative output is forcibly maintained at OFF regardless of the setting value.
