问题Hi-Flow™ control valves call out ANSI B16.104 Class IV flow leakage. What does this mean?

回答ANSI B16.104 is a testing specification for control valves. This specification has actually been superseded by ANSI/FCI 70-2 Class IV. The class IV designation defines the allowable amount of leakage through the valve seat in the closed position. Class IV allows for .01 percent of the rated flow (Cv), to pass through the seat. Class IV is common for metal to metal seated valves.

问题如果我需要HI-Flow™控制阀的零件怎么办?

回答Many Hi-Flow™ valves have been in service for 15+ years with all original parts. However, since Hi-Flow™ valves are commonly used in steam service, a severe application, some parts may wear over time. Unlike other control valves, Hi-Flow™ valves are designed with removable seat rings making repair or replacement of components an option. Although all parts are available, you will probably never need more than a seat ring, plug assembly, and stem packing to have a valve that is like new.

问题Why is the method of mounting a V4 of concern?

回答The vane and magnet keeper assembly near the hinge pin are very close to the mounting threads. Combined with the fact that pipe fittings are available in many variations, this produces a possibility that the customer will mount the switch in a fitting that prevents the vane from swinging. To make things worse, there is usually no way the customer can tell that this has happened. Mounting in a threaded branch connection avoids this clearance problem.

问题I am looking to measure velocity in a 4" pipe that is used as air conveyance. We use an eductor and a single stage blower to produce air flow. I am looking to measure pressure and velocity. I purchased a Dwyer Pitot tube, 167-7 108024-00 for the job, and I want to match with the right gauge. I need to be in the range of 2600 cuft/min at maybe 0.5psi. Can you direct me to the right gauge with that information?

回答To monitor flow through your 4” pipe, you will have to size the appropriate differential pressure gage. A very common gage that is used will be our Series 2000 Magnehelic gage. This gage can be ordered with a square root output that will direct read in flow units. Upon ordering this part, you will have to specify the maximum differential pressure at your desired flow rate. The following text will bring you to the equations necessary to compute this differential (velocity) pressure. This can also be found in the应用指南section of our website.

问题I am looking to use an "Air" flowmeter RMA-6-SSV to monitor CO2 flow. I am wondering if there are are any concerns or correction factors I need to apply.

回答A specific gravity correction factor will need to be considered when monitoring other gases with a meter calibrated for air. The correction factor equation is as follows: Q2=Q1 x sqrt (1/S.G.) Where: Q1= Observed Flowmeter reading Q2= Standard Flow Corrected for Specific Gravity 1= Specific Gravity of Air or Water S.G.= Specific Gravity of media being used in flowmeter originally calibrated for air or water.
This equation can be found in the beginning of the Flow section in the catalog. Alternatively, special ranges and scales can be provided; for specific information please contact our customer service department.

问题我最近购买了一个WM2-A-C-01,对于我的申请,管道是垂直的,水向下流动。说明提到它应该水平安装。是否可以垂直安装?

回答Multi-jet meters use multiple ports surrounding an internal chamber to create multiple jets of water against an impeller. The impeller rotation speed depends on the velocity of the water flow. If your water is flowing downward it will not rotate the impeller as it does in a horizontal pipe or in a up flow condition. Therefore, you cannot install this instrument in a vertical down flow application and receive accurate readings.

If you choose to have the NIST traceable calibration done, the NIST group (the National Institute of Standards and Technology) dictates yearly calibration and it will be printed on the certificate.

问题What might be the cause for Magnehelic® gages filling approximately 1/3 full of water, with lots of liquid droplets on the glass. Both are outside mounted on the side of an air stripping tower. One is a differential pressure gage that measures the pressure drop across a pitot tube. The other just measures the back pressure in the stripper. What can be done to fix the malfunction?

回答It looks like you’re getting some condensation in the Magnehelic®, which is causing it to collect on the bottom of the face. Since the Magnehelic® is not encapsulated, it is not recommended to be used in applications where moisture can form. One option to fix the problem is installing a liquid filter (like an F222) to filter out that moisture. Another option is to install a Capsuhelic (Series 4000), which is made to handle both air and liquid.

问题I have a LOVE 8C controller and am using the Controller Communication Utility (Model SCD-SW Configuration & Monitoring Software) to record data being sent to the PC through the USB cable. The data is displaying and recording, however all I can do to replay the data is to literally watch a video of the data as it was recorded. I am monitoring reactions that are hours long and it would be very helpful to model the data in Excel so that I can look at exotherms, manipulate the data quickly, etc. Is there a setting I am missing to export the data to time and temperature data points, or is this feature unavailable in the software. If unavailable, is there an update in the works to add the export data to excel function. Right now the software is slightly helpful, but not a strong "industry leading" type of software I would expect from Dwyer.

问题测量工艺管道中实际空气流量的最佳方法是什么,以验证过程空气流量传感器(差压传感器,空气流动站等)

回答有两种方法来测量空气流动过程ducts. The most common means is the use of a Series 2000 Magnehelic® Differential Pressure Gage. This gage can be ordered with a square root output that will read in flow units. You will have to specify the maximum differential pressure at your desired flow rate. Along with the gage, a pitot tube (connected by means of rubber or vinyl tubing) is also used. The pitot tube must be pointed directly into the air stream. Care must be taken to ensure that the pitot tube should be inserted at least 8-1/2 duct diameters downstream from elbows, bends or other obstructions which cause turbulence. The alternative method uses a 100 AV Durablock® Air Velocity Gage kit. The kit includes a manometer, a stainless steel pitot tube, rubber tubing with connectors, and red gage fluid. The pitot tube, pointed directly into the air stream, senses total and static pressure. The manometer then senses velocity pressure (difference between total and static pressure).

问题我有一个Digihelic DH007。我想知道是:我可以过滤输出继电器信号(设定点)吗?延迟或抑制功能是否在输出或仅在警报上工作?

回答由于诸如振动和过大的压力波动等事物,您可以使用抑制子菜单来稳定无限度的显示器。该阻尼特征将调整为每个显示更新的平均量的读数量。Digihelic DP控制器的功能与中继输出的“ALDL”报警延迟相同。但是,如果使用抑制功能,它不会像读取一样波动,因此不会导致读数超越设定点并激活交换机,除非它真正读取该压力。
