4 Notes You Must Know Selecting Portable Natural Gas Dew Point Meter

 

Portable dew point meter are a good tool for engineers working in the field and can be used in conjunction with online hydrocarbon and water

dew point analyzers to confirm natural gas quality. On-line analyzer provides continuous on-line measurement of hydrocarbon dew point (HCDP)

in natural gas. In contrast, portable dew point meters provide quick and easy testing of HCDP and water dew points at different sampling points in the system.  

 

First, Why is it Important to Measure the Dew Point of Hydrocarbons and Water?

Both hydrocarbon and water dew point are key parameters of natural gas quality. By measuring in accordance with ISO6327 or ASTM D1142,

all transmitted mass natural gas must comply with international gas quality specifications for transmission, storage, distribution and utilization,

such as CEN -- EN16726.

While online hydrocarbon and water dew point analyzers are installed at key points at each site (such as trade crossings in natural gas pipelines),

portable dew point instruments are important for engineers to test natural quality at different sampling points throughout the process. This allows

them to pinpoint leaks or deal with defects and identify any quality problems at a particular location. As part of a routine maintenance plan,

a portable dew point tester is often used to verify the online analyzer's measurements.

Hand-held portable dew point meter can quickly measure dew point data and calibrate the results of other dew point analyzers.

Second, How to Choose Portable Dew Point Tester

Several models of portable dew point meter and portable hydrocarbon dew point analyzers are available on the market.

These questions will help you compare the features and advantages of models on the market:

 

1. Does it have global danger zone certification?

   The ability to use a dew point tester to measure dew points directly in hazardous areas without the need for an active work permit means

that measurements can be made quickly and easily. For example, support personnel can measure quick responses through spot

checks to determine the cause of process disruptions. 

2. Is it light and portable?

    It goes without saying that a portable dew point measuring instrument needs to be easy to carry and have a long battery life so that

it can be reliably performed in the field and easily transported. Hengko 608 series dewpoint transmitters are portable and compact,

suitable for measuring gas pipelines, boxes and other narrow areas. 

3. Are the measurement results reliable?

    All manual visual portable dew point testers use cold mirror technology to measure hydrocarbon dew points. Although this is the most

reliable method of determining dew points, as it relies on direct observation of the actual formation of condensation on the cooling mirror,

there are differences in how the technique is applied. The ability to provide accurate and objective data for each measuring point is

also important when selecting an instrument, and not all models offer this. 

 

4. Does it meet international gas quality standards? 

   As mentioned above, natural gas must meet international standards such as CEN16726 or easee-gas cbp-2005-001-02. Any 

portable dew point tester must have the right precision to meet these requirements.
