The external clamp type ultrasonic flow meter is a common measuring instrument in industrial production because it has:
1 ã€Easy to install, non-contact, do not need to consider the liquid corrosion and process pressure, easy to install without interrupting the process;
2. No pressure loss, no moving parts, no maintenance;
3. The price has nothing to do with the pipe diameter, 15 mm to 4000 mm, the use price of large-caliber pipe has great advantages compared with Other flows;
4. Applicable to a variety of liquids, pipe material and flow range and other characteristics, is widely used by the favorite;
In the course of use, the clamp-type ultrasonic flowmeter will also encounter some failures, but if there is no professional guidance, some failures are difficult to handle. Jiangsu Xiangteng Instrument Co., Ltd. as a professional provider of ultrasonic flowmeter products and related services The professional manufacturers have summarized a set of effective solutions for the failure of ultrasonic flowmeters over many years of practice. The following is a summary of common problems encountered in the use of flowmeters and corresponding solutions.
?
Ultrasonic flowmeter uses the following 6 questions:
1 , the instrument is only backlit after power-on, without any character display The instrument only backlight after power-on, no other characters show this situation is generally a program chip loss, it is recommended that the instrument sent back to the original factory for processing.
2. No display at power on No display on power supply Check if the power supply attribute corresponds to the rated value of the instrument and whether the fuse is blown. If the above problem is not recommended, send the instrument back to the original factory for inspection by a professional technician.
3 , plug-in probe after a period of time to use the signal to reduce the probe into the probe after a period of time to reduce the signal may be offset or probe probe surface thick scale. The position of the probe must be readjusted to clear the probe emitting surface.
4. Ultrasonic flowmeter with external clamp type cannot use the instrument under strong field interference. The instrument cannot be used under strong field interference because the fluctuation range of the power supply is relatively large, there is a frequency converter or strong magnetic field interference around, and the ground wire is incorrect. Provide a stable power supply for the instrument, the instrument is installed away from the inverter and strong magnetic field interference, there is a good grounding line.
5 , Ultrasonic flowmeter signal low Ultrasonic flowmeter signal low mainly because the diameter is too large, the pipeline fouling serious, or choose to install the wrong way. For large diameters and severe fouling, plug-in probes are recommended, or the "Z" type mounting method is recommended.
6 , instantaneous flow value fluctuations large instantaneous flow value fluctuations in the performance of the signal intensity fluctuations and large fluctuations in the measurement of fluid itself. The solution is to adjust the position of the probe and increase the signal strength (maintained above 3%) to ensure that the signal strength is stable. If the fluid fluctuates greatly, it indicates that the selected measurement position is not good. It is necessary to reselect the point to ensure that the first 10D is 5D. Condition requirements.
Mold HVAC VENTS BEFORE AND AFTER
Mold infestation usually comes with a musty odor. If there is mold in your HVAC system, you should be able to smell the strange musty odor in multiple adjacent rooms. If the mold problem is quite severe, you should be able to spot the growth around the ducts, in the vents and the other parts of the ductwork. The spores are too small for spotting without specialized equipment, and you will not see any other overt signs until the infestation is rampant. In most cases, people have to rely on their sense of smell to detect the presence of this stealthy intruder in their homes.
What causes mold infestation in the HVAC air ducts?
A warm location with high water vapor content is particularly prone to mold buildup within the ducts. Water vapor can form within the duct system when cold air passes through, and when there is high water vapor content in the outside environment, the water droplets usually collect instead of evaporating. It forms the most conducive environment for mold growth. The nutrition for the mold usually comes from dust, dirt, dead skin cells, pollen, and animal dander that collects over months inside the duct along with the water.
What are the signs of mold in air ducts?
Here are a few definitive signs of mold growth within home HVAC systems:
A strong mildew-like or musty smell throughout the house or at least in a few adjacent rooms.
Your nose, throat, and eyes feel irritated when you switch on the air conditioning or step inside an air-conditioned room.
You are experiencing allergic symptoms including a runny nose, rashes, and watering eyes.
You or your family is suffering from unexplainable headaches that go away when you step outside.
You feel nausea, fatigue, and dizziness only when you are home.
You can see the mold growing within the intake vents and around the air ducts and drip pans.
Therefore, if you live in a warm climate and your home smells musty all the time, you have the perfect reason to suspect a mold infestation within the central air conditioning system. You should never wait for the visible signs of infestation to manifest before taking action. You may not be able to see specific sections of your HVAC ductwork from the outside. In that case, you should ask for professional help.
How can homeowners tackle the problem of mold and how to get rid of mold in air ducts?
Sometimes, the mold problem is not overwhelming, and homeowners prefer to deal with the issue on their own. It calls for some robust DIY mold removal techniques. The EPA recommends the employment of professional mold removing services when the suspected mold cover spreads over ten sq ft. If the infestation in your heating ducts is not as severe, you can try removing the growth with ingredients that you can find at your local Home Depot. Here is information on how to get rid of mold in air ducts.
Removing Mold from Your HVAC System:
Selection of the cleaning solution is the first and the most crucial step that decides the fate of the HVAC system inside your home and ultimately if you are successful in how to get rid of mold in air ducts. The cleaning agent you choose can either remove mold or let it fester secretly. Therefore, you need to be cautious when selecting a DIY solution for your mold problem.
