Intelligent DN50 gas Roots flowmeter DN50 aluminum alloy gas Roots flowmeter

Description :

　　This product mainly consists of three parts: measuring chamber, sealed coupling, and counter. It can indicate cumulative flow and instantaneous flow on site, equipped with a transmitter and intelligent flow controller, and can achieve remote measurement and control.

　　1、 Product Features

　　1. Wide range and low initial flow rate;

　　2. There is no need for straight pipe sections before and after the flowmeter, which occupies less space;

　　3. Low power consumption, one 2 # 3.6V DC lithium battery can run continuously for more than two years;

　　4. LCD displays various parameters under working or standard conditions, with complete functions;

　　5. Can be used in conjunction with IC card prepaid system;

　　6. Can be connected to the customer's remote data collection system to achieve centralized data collection and real-time management;

　　7. It has user password setting and power down protection functions.

　　2、 Technical parameters

　　3、 Installation and use

　　(1) A filter should be installed in front of the flowmeter, and the arrows on the meter body of both should point in the direction of flow*

　　(2) When the measured liquid contains gas, a gas separator should be installed in front of the flowmeter

　　(3) Regardless of whether the pipeline is installed vertically or horizontally, the waist wheel axis of the flowmeter should be installed in a horizontal position (i.e. the dial should be perpendicular to the ground).

　　(4) If it is difficult to see the reading clearly when the flowmeter is installed correctly, the counter can be rotated 180 or 90 degrees.

　　(5) The throttle valve should be installed at the inlet of the flowmeter, and the on-off valve should be installed at the outlet. When using the on-off valve, it should be started slowly and not suddenly opened.

　　(6) It is strictly prohibited to use sweeping steam to pass through the flow rate

　　(7) In the continuous use department, a bypass pipeline needs to be added to the flowmeter

　　(8) Before installing the flowmeter, the pipeline needs to be flushed. During flushing, a straight pipe section (replacing the position of the flowmeter) is used to prevent welding slag, debris, etc. from entering the flowmeter
