Down Hole Flow Logger ,know as Bore Hole Flow Logger,is a device used for water well testing or monitoring ,Meinte instrument can provide high precision flow measurement with very wide flow range. Our instrument has no moving parts ,free maintenance, corrosion proof and sediment resistant and other unique advantages of strong and reliability. It is an idea equipment (tool) for water well monitoring . To Analysis of water well reservoir layer productivity and water quality ,like PH and water conductivity .etc
Features
1) It can work in very deep down-hole with long-term, without any external equipment. Detection, signal processing, computing data storage, communications are integrated. All logging data can be read out by special acquisition software online ,read time collect first hand origin data
2) Adopts small surface-mount components, micro-power CPU chip and memory. Small size, low power consumption, intelligent, Small output communication interface
3) High pressure: Generally resistant to 40Mpa, the highest 80Mpa. High Temperature: All components used military long-term use temperature of 125Deg C, maximum temperature 150Deg C (special 175Deg C). Relative humidity: Immersed into the medium under high pressure
4) Electronic acquisition system: This instrument use special software and meter, the instrument automatically measure the flow of each well, pressure and temperature of the raw data processing order to achieve the automation of statistical measurement of water injection wells
Function
1) Flexible software, downloading data to a PC, viewing and printing out measured data as tables or charts.
2) Measurements can be started at a set value of time, flow fluid, pressure or temperature
3) To read out all the data sets through log acquisition software
4) Randomly calculate flow rate function
5) Sampling, real time values (instantaneous value), average value , etc
6) List historical data and Draw out the diagram of the historical data according to time
7) Environmental correction algorithms are included within the acquisition software.
8) Specially for water well monitoring oil/gas and Coal bed methane operations
Application
1)  Borehole testing and logging.
2)  Well surveys, well inspection.
3)  Investigation of existing water wells
4)  Groundwater exploration and management.
5)  Complete chemical and physical analysis of ground water :PH ,EC ,temperature etc
6)  Development and clean water wells tests.
7)  Water well yield tests, water well productivity test, water well continues discharge tests
8)  Water well constant rate discharge tests
