1. How much water should be added to the LMF-2 wet flowmeter? The commonly used Ziyou Instrument series LMF wet flowmeter is corrosion-resistant and made of stainless steel material, which can measure corrosive gases. The usage method of LMF-2 Ziyou wet flowmeter is as follows:
1. Place the instrument on the workbench, adjust the corner screw to make the water bubble on the level center, and maintain it for a long time during use. Open the sealing nut of the water level controller and pull out the internal yarn rope. Inject distilled water into the thermometer or pressure gauge socket, and stop injecting distilled water when it flows out of the water level controller hole.
2、 When the excess distilled water from Yuanchang flows clean and tidy along the yarn rope from the water level controller hole (when a drop flows out for a long time, it is considered clean and tidy), put the yarn rope into the sealing nut of the water level controller and tighten the sealing nut tightly. Install the thermometer and pressure gauge. Connect the air path in the direction of inlet and outlet (10Pa per small grid) and seal it. Open the gas valve to perform gas measurement. The precautions for LMF-2 self regulating wet flowmeter are:
1. During use, it is important to regularly maintain the water level inside the instrument, otherwise it will affect the measurement accuracy. During use, the temperature should be maintained between 15~25 ℃, and the temperature difference between the temperature and room temperature should be ≤ 2 ℃. It is best to take readings after the instrument pointer has run for several cycles. When the pressure of the measured gas exceeds the normal pressure value by 1-6 times (1-6 Kpa), the instr
2、 When the flow rate of the measured gas exceeds the rated flow rate and is used within the excess flow range, the instrument can still operate, but the measurement accuracy will be reduced at this time. When the instrument is not in use for a long time, the distilled water inside the instrument should be drained clean and tidy. When draining, use a drain valve first, then lower the meter head, and then lower the exhaust pipe. Repeat this process several times before draining the water inside the drum. Instruments should not be installed in supercooled rooms to prevent internal icing. Under normal usage, the accuracy should be checked at least once a year.
2. How to make distilled water in the laboratory and what equipment is needed
Generally, an electric still is needed for making distilled water in the laboratory, and the appropriate equipment specifications should be selected according to the size of the laboratory.
. The following are the main equipment and brief description required for making distilled water: Electric distilled water dispenser: Function: To evaporate water by heating, and then condense it into pure distilled water. Specification selection: According to the actual needs and scale of the dust laboratory, different specifications of electric distilled water dispensers can be selected, such as 5L/h, 10L/h, 20L/h, etc., corresponding to the production of 5 kilograms, 10 kilograms, and 20 kilograms of distilled water per hour, respectively. Water source: A clean, tidy, and impurity free water source is required
