    Insertion type Magmeter?

    BioEngr, It sounds like the problems the other people had with insertion mags were application based. If aplied well, they are a fine technology. Are they as good as a full bore magmeter? No. Are they an adequate low cost alternative to them for most applications? Yes. As long as you know...

    heating coil material for use in Sodium Hypochlorite

    Russiangoat, As you stated, painting the SS would be a bandaid solution. Without knowing anything about the membranes, it is impossible to say if they would be damaged. What type of pressure will they be subjected to? What material are they constructed of? PTFE should work just fine with a...

    heating coil material for use in Sodium Hypochlorite

    MJC, There are several manufacturers for these types of products. We have used the ones made by Process Technology. www.process-technology.com How long the coil lasts is application dependent. They are commonly used in metal finishing. Glenn

    pH measurement of oily water after gas/water separator

    Mettler Toledo makes a very nice automatically retracting pH probe that is suitable for your application. I believe that it is they type of setup that M777182 was referring to.

    heating coil material for use in Sodium Hypochlorite

    Russiangoat, Do NOT use SS with Hypochlorite. It is exceptionally bad for that service. Not only will it likely corrode in a week, but the metal contamination that it will cause in the Hypo will make the Hypo much more agressive as a stress cracking agent down the line in your piping, tanks...

    Sodium Hypochlorite Injection

    A couple of suggestions here: First for the person asking about what type of floats to use. PVDF should work fine. Definitely go with plastic materials for this application. As far as the pumps go, I would definitely agree to get away from the solenoid driven pumps at that pressure. I do...

    Level Meas with foam over liquid?

    Fixerman, Your application is a complex one. I would not recommend a pressure based system because of the changing densities. How large is your tank? Radar sounds like it would be the most bulletproof approach (not that any level technology is completely bulletproof). If price is an issue...

    pump for slurry, rubber lined vs alloy vs plastic

    Slojim, If your slurry is abrasive, plastic pumps may be a very good way to go. Plastic pumps actually have much better resistance to abrasion than lined or even metal pumps. Vanton published an excellent technical article on this topic several years ago that I can forward to you. What is...

    4-20mA to HART Converter

    Schlebda, Mescon Technologies makes a signal converter that can convert a 4-20mA signal to HART. I think it is their SST200. They may have other units too. We have used there equipment very successfully in our systems and they are very nice people to deal with. Here is their contact...

    Portable Flow Meters

    Jeff, You mentioned that reverse flows are a possibility. Do you want to measure the reverse flow? As far as technologies go: 1. Mag meters are going to be extremely expensive at the very large pipe sizes. They will work well however, and are a good selection. 2. Transit time ultrasonic...

    Chemical Feded Pump Drive Question

    TGreif, We sell a lot of chemical feed pumps. In the last several years there has been a growing movement of using AFDs. It is perfectly acceptable to use either an AFD or a DC drive for this service, and in most case just a matter of style preference. I personally prefer using the DC drives...

    emission control wastewater discharge

    Vintage, I believe that the materials from the University of Toledo WW treatment course listed the different classifications. If you would like to email me your contact info to glenn@panner.com, I will send you a copy of what I have. Glenn

    Effect of pH on ppm readings of Ozone by ORP?

    I know that when you measure the ppm of Chlorine in water by ORP that pH is an important variable. There are many charts that show this relationship. When ORP is used to measure Ozone, does anybody know if these same type of charts exist? Is the measurement reading of ORP in mV tied to pH in...

    pH for removal of NH3 from exhaust with dilute H2SO4 Scrubbing?

    Your best bet is to contact the manufacturer of the packing material who can tell you the pH where you will have the best efficiency. The chances are that you will need an acidic pH, so a PVC scrubber will probably be the best choice.

    Ultrasoic flow meters

    Joisy, What do you have going through the pipeline? There are two types of Ultrasonic flow meters, Doppler and Transit time. Doppler is the older technology of the two and works very well on dirty liquids, and liquids with solids. With this type of meter, an Ultrasonic pulse is projected...
