The method comprises the following specific steps:
firstly, detecting the pressure of hydrogen at the outlet of the hydrogen production machine:
considering that the output pressure of the hydrogen production machine is adjustable, and the maximum pressure can reach 2MPa, the pressure range of an instrument selected for detecting the outlet pressure of the hydrogen production machine is satisfied as follows: 0-2MPa, and the use temperature range meets the requirements of the hydrogen production machine during normal operation: -20 to 80 ℃.
Hydrogen flow detection at the outlet of the hydrogen production machine:
the outlet flow of hydrogen of the hydrogen production machine can change along with the difference of input power, when the hydrogen production machine works at the maximum input power, the output flow of hydrogen can reach 1000NL/h, and the measuring range of a flow sensor is selected as follows: 0-1000 NL/h.
Thirdly, detecting the pressure before/after the hydrogen production and electrolysis water pump:
because the estimated water tank size is 1 x 1m, the pressure before the electrolysis water pump is very small, the maximum pressure of the water before the pump is calculated to be 1kPa, the pressure after the pump is improved according to the selected small water pump, and the maximum pressure after the pump is 15kPa according to 15 times calculation. The pressure range of the pre-pump meter is therefore chosen: 0-1.5kPa, gauge pressure range installed after pump: 0 to 15 kPa.
Fourthly, detecting/controlling the liquid level of the water replenishing tank:
the size design of moisturizing case is 1 x 1 m's water tank, can see that the change of liquid level is between 0-1m, but requires its minimum liquid level to detect 0.05 m's precision, accurate detection when just so can realizing the low water level, timely moisturizing, so the level sensor's of chooseing for use scope: 0-1m, and the precision requirement reaches 1%.

The maximum hydrogen release pressure is 0.3MPa, the regulation can be realized, the range of the selected pressure gauge is 0-0.3MPa, and the precision requirement is 3%.
