E+H mass flow meter
Thread Content
Can a Promass 80 mass flow meter be purged with ordinary steam? What is being transported through the pipeline is anthracene oil from the coal chemical industry; is it better to install it horizontally or vertically?
Why is purging necessary? It is recommended to use alcohol for cleaning. If purging is required, use instrument air for it, but the pressure must be adjusted to within the range that the instrument can handle. The liquid should be measured with it installed horizontally, with the shaking tube at the bottom.
Mass flow meters that are not heat-resistant cannot be purged with steam; they can be installed either horizontally or vertically, as long as the tank is filled.
First, check what the maximum temperature tolerance is for this flow meter during operation; if the temperature meets that requirement, it can be used
Can it be purged with steam? We know that the pipe wall is made of stainless steel or even special materials, and there are circuit boards inside. The instructions do specify the allowable temperature, but in actual use, if blockages occur or other situations arise that require steam cleaning, then there’s nothing that can be done about it.
Check the operating temperature of the flow meter; excessive temperature can affect the lifespan of electronic components
We also use E+H mass flow meters to measure the residue; before calibration, we blow it with steam to prevent residue from remaining, and there are no issues
Mass flow meters generally can withstand temperatures of up to 200 degrees; using steam at temperatures below 200 degrees for purging poses no problem at all. For fluids containing impurities and prone to crystalline scaling, vertical installation with flow from bottom to top is recommended.
It still depends on the data sheet for your specific model, as it contains information regarding temperature and pressure
It can be installed horizontally or in a flag style; it should also be placed in areas where vibrations and stresses are low. The flag style makes it easier for dirt to slide off. Steam is fine; we have blown on it, and we can also check the steam flow rate.
First, check the operating temperature specified during selection to determine whether it is a high-temperature version. Both E+H models come with installation manuals, and whether to install them horizontally or vertically depends on the layout of the pipes on site.
