Â Â LZDZ Series Auto Batch Control Flow MeterÂ is designed by our company for liquids control and preciseÂ measurement (hereafter we call LZDZ). LZDZ has the feature of compact structure, easy operation and stable performance. According to theÂ preset flow value, LZDZ can control the process flow automatically and measure it precisely. In loading/unloading system, LZDZ can detect theÂ many signals such as electrostatic grounding, high level alarm and then operate automatically and safely. Through remote communication, LZDZ can also compose the Collecting-Distributing Quantitative Filling Control SystemÂ with upper computer for rationing oil, which includes the functions of monitor, query and printing.

Â Â Unloading
Â Â Filing
Â Â Â Structure
Â Â LZDZ is made up with flowmeter, valve and controller and can be installed directly in the loading/unloading pipeline through flanges to control the measurement automatically.
Â Â 1. Flowmeter
Â Â Adopt our LSZ Series Double Rotator flowmeter or other kind of flowmeter;
Â Â 2. Valve mechanism
Â Â Adopt electric operator and ball valve.
Â Â 3. Controller
Â Â Adopt single chip, array LCD and 15*10 field key operations.
Â Â Installation
Â Â Â 1. Installation Environment
Â Â Please confirm the environment is suitable for the performance marked on the nameplates before install the LZDZ in hazardous area (except coal mine).
Â Â 2. Location
Â Â LZDZ can only be installed horizontally and meanwhile should be kept the pipeline for measurement full of the process liquid.
Â Â 3. Direction
Â Â Please install LZDZ according to the correspondence between Flow Arrow direction marked on body and the Flow Direction in the pipeline or indicate the flow direction and operation location before placing order.
Â Â 4. Installation Instruction.
Â Â Please mount the two flanges of LZDZ into the pipeline and meanwhile keep some space for operation panel which should be convenient by the operators.Â
