Introduction

The  online  crude  oil  water  content  analyzer   installed  under  pressure  uses electromagnetic  wave  phase  shift  detection   technology  to   measure   the  dielectric constant of crude oil. Based on the comprehensive dielectric constant of the mixed liquid,  the  water  content of crude  oil  is calculated.   This  technology is a  mature technique widely adopted and recognized by foreign petroleum instrument companies for stable, accurate, and reliable measurement of crude oil water content.

The moisture content analyzer adopts an integrated dedicated chip as the core measurement  unit.   The  use   of  high-tech  chips  makes  the   instrument  have   the characteristics of small size,  large measurement range (0 -100%), high measurement accuracy, good working stability,  and easy installation.

The water content online measurement technology can achieve comprehensive water content online  measurement monitoring, remote data  transmission,  real-time online monitoring of comprehensive water content, and integrate with existing digital platforms to monitor and record the water content changes of crude oil in pipelines in real time, meeting the needs of production  sites.

Scope of application

1. Online water content detection of various fluid media in well sites, joint station oil pipelines, and chemical plants;

2. High water content and low water content crude oil, exported crude oil, benzene and other organic liquids;

3. It can also be used for measuring the moisture content of liquids in oil storage tanks and irregular containers.

4. No pipeline shutdown or pressure relief is required during installation, achieving rapid installation of pipeline moisture analyzer

Product features

1. The electromagnetic wave phase shift detection technology is used to measure the dielectric constant of crude oil, which can be used immediately after power on. It does not  contain  any  radioactive  substances  and  has  no  moving  parts,  ensuring  high measurement  resolution   and   strong   medium   adaptability.   It   is   also   safe   and environmentally friendly, and can directly replace the early installed radioactive water content instruments in oil fields.

2. The header adopts explosion-proof technology, with real-time display of Chinese text and numbers, making debugging convenient.

3. Unique pipeline non-stop transmission and pressure relief installation structure, fast and convenient installation

4.  Built-in  temperature  sensor,  as  the  dielectric  constant  of water  decreases  with  increasing temperature, it can lead to a decrease in the measured moisture content value. Temperature compensation can accurately correct the measurement results, thereby  achieving the goal of improving measurement accuracy.

5. The instrument probe is made of stainless steel and can adapt to various corrosive liquids such as acids and alkalis, as well as the vast majority of tested media including organic solvents such as toluene.

6. Intelligent communication, software can be upgraded on-site.

7. The product has no mechanical moving parts, and with the surface treatment process of anti sticking oil, it ensures the long-term reliable and maintenance free operation of the instrument.
