Electric remote transmission wet gas flowmeter/wet gas flowmeter (anti-corrosion 5L stainless steel) model: TR-LMF-2

1、 Product Overview

TR-LMLThe type is ordinary, made of brass material, and is generally used in a non corrosive gas range.
TR-LMF type is anti-corrosion type, made of stainless steel material, and can measure corrosive gases

2、 Usage method
1. Place the instrument on the workbench, adjust the corner screw to center the water bubble on the level, and maintain it for a long time during use.
2. Open the sealing nut of the water level controller and pull out the internal yarn rope.
3. Inject distilled water into the socket of the thermometer or pressure gauge, and stop injecting distilled water when it flows out of the water level controller hole. When the excess distilled water flows out of the water level controller hole along the yarn rope and is clean (when a drop flows out for a long time, it is clean), put the yarn rope into the sealing nut of the water level controller and tighten the sealing nut tightly.
4. Install the thermometer and pressure gauge. (10Pa per small grid)>
5. Connect the air path in the direction of inlet and outlet, and seal it.
6. Open the gas valve to perform gas measurement.

3、 Precautions
a) During use, it is important to regularly maintain the water level inside the instrument, otherwise it will affect the measurement accuracy.
b) During use, the temperature should be maintained between 15~25 ℃, and the temperature difference between the temperature and room temperature should be ≤ 2 ℃.
c) Read the instrument pointer after several cycles of operation.
d) When the pressure of the measured gas exceeds the normal pressure value by 1-6 times (1-6 Kpa), the instrument can still work. At this time, the pressure gauge should be removed and the installation hole of the pressure gauge should be blocked with a non porous rubber stopper.
e) When the flow rate of the measured gas exceeds the rated flow rate and is used within the rated flow rate range, the instrument can still operate, but the measurement accuracy will be reduced at this time.
f) When the instrument is not in use for a long time, the distilled water inside the instrument should be drained completely. When draining, use a drain valve first, then lower the meter head downwards, and then lower the exhaust pipe downwards. Repeat this process several times before the water inside the drum can be drained completely.
g) Instruments should not be installed in supercooled rooms to prevent internal icing.
h) Under normal usage, the accuracy should be checked at least once a year.

4、 Accessories
Random attachment: 1 thermometer, 1 pressure gauge, 2 rubber stoppers
