Product Description
The ATWY threaded liquid turbine flowmeter structure is explosion-proof and can display the total flow rate, instantaneous flow rate and flow full percentage. The battery uses a long-acting lithium battery, the service life of the single-function accumulator battery can reach more than 5 years, and the service life of the multi-function display battery can also reach more than 12 months.
The threaded liquid turbine flowmeter is a kind of precision flow measuring instrument, which can be used to measure the flow and total amount of liquid with the corresponding flow integrating instrument. Widely used in petroleum, chemical industry, metallurgy, scientific research and other fields of measurement, control system. Threaded liquid turbine flowmeter sensors with sanitary fittings can be used in the pharmaceutical industry. It has the characteristics of simple structure, light weight, high precision, good repeatability, sensitive response, easy installation, maintenance and use of the new generation of threaded connected liquid turbine flowmeter.

Installation Instructions
- Requirements for the straight pipe section: The flowmeter must be installed horizontally on the pipeline (the inclination of the pipeline is within 5), and the flowmeter axis should be concentric with the pipeline axis when installed, and the flow direction should be consistent. The length of the upstream pipe of the flow meter should be not less than 2D equal straight pipe section, if the installation site is sufficient, it is recommended that the upstream straight pipe section is 20D and the downstream is 5D.
- Requirements for bypass pipes: In order to ensure that the normal use of the medium is not affected when the flow meter is repaired, a cut-off valve (stop valve) should be installed on the front and back pipes of the flow meter, and a bypass pipe should be set up. The flow control valve should be installed in the downstream of the flow meter, and the stop valve installed in the upstream when the flow meter is used must be fully opened to avoid the unsteady flow of the upstream part of the fluid.
- Requirements for the external environment: When the flow meter is installed indoors, it must be installed outdoors, and it must use sun protection and rain protection. Lightning protection measures to avoid affecting the service life.
- Requirements for impurities in the medium: In order to ensure the service life of the flow meter, a filter should be installed in front of the straight pipe section of the flow meter.
- Installation location: The flowmeter should be installed in a place that is easy to maintain and free from strong electromagnetic interference and thermal radiation
- Requirements for installation and welding: The user has another pair of standard flanges welded on the front and back pipes. Welding with flow meter not allowed! Before installing the flow meter, the welding slag and other dirt in the pipe should be strictly removed, and the pipe of equal diameter (or by-pass pipe) should be used to replace the flow meter for purging the pipe. To ensure that the flow meter is not damaged during use. Installation flow time, flange between the sealing gasket can not be concave into the pipeline.
- Flowmeter grounding requirements: the flowmeter should be reliably grounded and cannot be shared with the ground wire of the strong current system.
