What matters should be paid attention to in the operation of purified water system? 1. the hydrolysis of the reverse osmosis membrane of purified water equipment is easy to cause the performance of the reverse osmosis device to deteriorate,To this end,The pH value of water must be strictly controlled,The pH value of water supply is 3-Within 11.2. when the amount of sodium hydroxide injected is insufficient and the free chlorine in the water supply cannot be measured,There will be sticky mud on the membrane assembly of the reverse osmosis device,The differential pressure of the reverse osmosis device will increase.But for the polyamide film,The amount of free chlorine entering the membrane assembly must be strictly controlled,Exceeding the specified value will lead to oxidation and decomposition of the membrane.3. if the water supply reverse osmosis device with the FI value exceeding the standard is used as water supply,Dirt will be attached to the surface of the membrane assembly,This must be remove
Difference between filter and sampling device of water quality meter Generally, the flowmeter that can measure the liquid is combined with the paperless recorder.There are many kinds of combinations here,Paper-free recorder for magnetic flowmeter,Paper-free recorder for liquid turbine flowmeter,Vortex paperless recorder,Ultrasonic paperless recorders, etc,The specific choice of use depends on your installation environment,If there is a large motor or magnetic field interference in the installation occasion, the accuracy of the use of the magnetic flowmeter will be affected.If there are more impurities or filament wound in the measurement medium,I don't agree with turbine flowmeter,This is afraid that the winding material in use will affect the use of the turbine.You also have an RS-RS232 C/RS-Communication interface 485,Remote monitoring can be achieved,Manage the data recorded on the paperless recorder.
