Ultrasonic Flow Meter 5v1

this brand is a very reduced version of the 3v2 version to respond to a rude environment (such as on the mountain and in deep water, where no electricity or power supply exists), optimized in components, programmed. It is precise.  

How to read the Flow Value (liter/min) ? just plug 12 Volts Battery (+, -) to the flow meter.  The current circulating is Std 4-20mA, then read it in voltage through a resistor to the ground (plug -).  50 Ohm< Resistor < 500 Ohm, typically 100 Ohm.

Price: < 100 Euro (Valve not included).

Deviation: expected 0.25%.

Input DC Voltage: 12 to 36 VDC

Equipped with:

• M12 Connector (2-positions), it can be replaced by any customer proposed.

Output Signals

• Standard 4-20mA,
• Hart (option, but not yet tested), 

Reliability:

• running 2 years non Stop with no single damage or whatever.
• output current 4-20mA is protected against short to ground.
• PCB Temperatur < 25°C 

Dimensions: 60 x 42.5 x 10 mm (mounted Plug M12 is included).
