    PORTABLE MOISTURE GENERATOR

    Thank you guys. For Sparky, I want to order a bottle of standard gas for our analyzers (moisture in butane, instrument air and propane). Can you help me about the gas. Is the gas nitrogen with a specified moisture content? and what about the litters of the bottle? bY the way our...

    PORTABLE MOISTURE GENERATOR

    SOrry , i don't understand what you mean (Bribyk). Do you use N2 standard only for this purpose (for moisture analyzer)? Or do you mean pure N2 (99,999%) that we use as carrier gas for chromatographs? What i want is to be sure for the proper operation of the moisture analyzers. Thanks a lot...

    PORTABLE MOISTURE GENERATOR

    I want to test if the moisture analyzers are working properly. I want an easy handling, not heavy and a reliable portable moisture generator. Is there any suggestion? Thanks in advance. REMEMBER IT IS NOT GREECE IT IS HELLAS

    Boiler Level

    Sorry it is not actually boiled water. It contains some chemicals. I just wrote it like this to be more understood. Apparently, i was more confusing. REMEMBER IT IS NOT GREECE IT IS HELLAS

    Boiler Level

    In one of our boilers we have got level with displacer. The s.g of the liquid (boiled water) is more or less 0.85. We calibrated with water and then from the parameters we changed it at the correct s.g (Masoneilan). The level was at 15% (glass) and it appeared at the instument 0% . Any...

    PLC LOSS OF MEMORY

    Hello, Suddenly i found Allen Bradley plc without memory. Everything was red. The bat led was red and the led of o.k. too. The plc has UPS support and as i saw in the manual there is no reason to lose memory from a problem of the power supply. The operator told me that he found it in this...

    CONDENSATE PROBLEM

    Thank you a lot. It is a heated transport tubing from the chimney (67meters long) and just 50 cm without heated cover. I have a water trap from abb but believe me every two days i have to press air backward to the line. I will try one of the filter from the site you recommended. <<<<Thank you...

    Level, flow, pressure transmitters

    I forgot to write you that Masoneilan (Dresser) are very good for level instruments (if you will use with displacer). REMEMBER IT IS NOT GREECE IS HELLAS

    Level, flow, pressure transmitters

    I think rosemount are the best. They are very easy to use them and if you have a HART you will not have a prblem at all. Honeywell are not bad but we don't trust them a lot. REGARDS HELLINAS REMEMBER IT IS NOT GREECE IS HELLAS

    2 Liquid Level Measurment

    There is a level istrument from Enraf (we use it). With a float you can measure the oil and when you want you can measure the water. The principle is based on detection of variations in the buoyancy of a displacer. The apparent weight of the displacer is measured by a force transducer. So...

    CONDENSATE PROBLEM

    Hello , I have a big problem at the analyzers of the refineries with the condensate of the sampling system. I tried some pots or some water traps but nothing. Is there any practical way to solve the problem? THank you in advance. REMEMBER IS NOT GREECE IS HELLAS
