Thermal mass flow meter wiring and connection instructions

 


Wiring for 4-20 using the Internal 24 VDC power supply from the Mass Flow Meter.  Be sure to place the jumper to the INT position. This is the easiest method of outputting 4-20 mA for 0 to Full Scale. DO NOT USE this method if you are using a PLC or device that has POWER. This method can ve easily read with a DVM configured to read current as shown above. The advantage of this method is near immunity to noise. Frequently users use 4-20 mA to drive the current across a 250 Ohm Resistor and simply measure 1 to 5 VDC for 0 to Full Scale. Read more

How Thermal Mass Flow Meters Work

Image
The video below shows how the Tactical Flow Meter works and what advantages it has over conventional Thermal Mass Flow meters, such as the Sierra Instruments Model 840 or Sierra Instruments Model 830 series Thermal Mass Flow Meters that I worked with John, Dick, and James that we designed over 25 years ago. The Tactical Flow Meboasts a power fail tolerant datalog storage system that is a significant improvement over conventional “SD Card” file storage/file management systems. While both our datalog storage system and a conventional “SD Card” storage systems utilize flash storage technology our storage system concatenates each event or data at the end of the file using a simple pointer system where the pointers stored in EEPROM and the data is stored sequentially after the last event. If the power goes out in the middle of a storage event in a conventional “SD Card” system and the entire file can be lost.  If a power outage occurs during the middle of writing an event in our storage sys
