Pyxis Lab, Inc. Standard Limited Warranty Pyxis Lab warrants its products for defects in materials and workmanship. Pyxis Lab will, at its option, repair or replace instrument components that prove to be defective with new or remanufactured components (i.e., equivalent to new).
The FS-100 series flow meter is powered by a 24 VDC/1 W power supply and provides both 4–20 mA and RS-485 Modbus output signals for connection to any OEM controller, PLC or DCS.
20mA output is internally connected and used to control the regulating valve. Specifications are subject to change without notice. (2) Refer to Ryton PPS chemical compatibility prior to use for measurement of any chemical or corrosive aqueous solution. 21242 Spell Circle, Tomball TX service@pyxis-lab.com +1 (866) 203-8397...

(pyxis-lab.com) 3.2 Optional/ Replacement Accessories The following optional accessories can be ordered from Pyxis Customer Service (order@pyxis-lab.com) or Pyxis E- Store at https://pyxis-lab.com/shop/ Table 2.
2 × M4 Nuts Panel Mounting Procedure: Use the mounting plate on the back of the FS-100 as a template to mark the positions of two holes. Drill the holes: Ø 4.2mm Figure 3. 21242 Spell Circle, Tomball TX service@pyxis-lab.com +1 (866) 203-8397...
4.4 Nano-Flow Control Module Sold separately, the Pyxis Nano-Flow Control Module is a stand-alone water flow measurement and control solution designed for use in critical cooling and process-water sample flow applications. This unique platform provides precise flow measurement and regulation and may be installed upstream of inline sensors in water systems that are subject to pressure and flow variation challenges.
Lead Cable (P/N 50762) that is provided with each FS-100 flowmeter package and refer to the wiring table below for proper wiring. *NOTE* Pyxis offers outlet plug in power supply adapter cables in both USA-Type A and EU-DIN formats for those desiring to power the FS-100 series via outlet. See Optional/Replacement Accessories Section 3.2 for details.
6. FS-100 Series Operation 6.1 Key Function Enter Key - Main screen Setting Menu. - Confirms and saves the input values. Left / Right Key - Main screen Trend Chart. - Move the cursor to the left or right. - Turn pages on the screen.
Once the flow rate value exceeds the alarm upper limit or falls below the alarm lower limit, and the duration time is longer than the user programmed detection time, the main screen and LED indicator will display a alarm status as shown in Figure 8. Figure 8. 21242 Spell Circle, Tomball TX service@pyxis-lab.com +1 (866) 203-8397...
⚫ Flow Control* = Set a desired constant flow rate. *NOTE* The Flow Control mode should be used with a regulating valve. Pyxis offers a “Turn-Key” flow control solution called Nano-Flow , please refer to Section 4.4 for more details.
6.6 Flow Regulating Valve Output - 4-20 mA Span The FS-100 series flow meter controls the valve position of the regulating ball valve by outputting the 4-20 mA signal. After the user assigns a desired flow set point in Flow Control (C) mode, the FS-100 series will automatically calculate the error between the actual flow rate and the setpoint flow rate and adjust the appropriate 4-20mA output value through the preprogrammed PID algorithm to regulate the valve.
Zero Calibration: This function is used to correct the instantaneous flow rate to “ZERO”. *NOTE* To perform zero calibration the pipe must be filled with fluid and the fluid should not be moving. Figure 15. 21242 Spell Circle, Tomball TX service@pyxis-lab.com +1 (866) 203-8397...
If the calibration was successful, the interface will return a message “calibration succeed”. 6.9 Display Screen Orientation Settings Press in the setting menu and select [Screen] to select the display orientation of the screen.

Communication Using Modbus RTU The FS-100 series ultrasonic flowmeter is configured as a Modbus slave device. In addition to flow rate ℃ mL/min and temperature values, many operational parameters, including warning and error messages, are available via Modbus RTU connection.
