What is a Flow Meter Transmitter?
This is a pulse transmitter that counts pulses from a flow sensor on its signal input from 1Hz up to 100kHz. This device converts the pulses into liters or gallons, depending on the settings. By turning on the Wi-Fi connection on the module, we can reach the web user interface where all settings can be changed, and the actual values can be read. On this interface, we can give the calibration values too.
It has two analog signal outputs: The totalizer output and the actual flow rate output. Both have 0-10V signals.
The Modbus output transmits the actual flow rate, the resettable totalizer, and the non-resettable totalizer values.
The module needs a power supply from 18-30VDC. It has a 15V / 500mA output for supplying the flow meter sensor and/or the external reset button which you can use to reset to zero the outputs.
Where can you use this product?
It’s an ideal choice to measure the volume of transferred fluids or air using a proper sensor. You can use it for water treatment applications, and automation projects, where you need to know the exact amount of the use fluids or air.
