Lithium battery powered vortex precession gas flow meter
Basic Info
Model No.: LUXBZ
Product Description
Intelligent vortex precession flow meter is a new Gas Flow Meter with the leading domestic level which is developed by our company. The flow meter has a combination function of flow, temperature and pressure detection. It also has the function of temperature, pressure and compression factor automatic compensation. It is the ideal instrument that is used for gas metering in petroleum, chemical industry, electric power, metallurgy and other industries.
Intelligent vortex precession flow meter can be widely used in the measurement of various gas flow in Petroleum, chemical industry, electric power, metallurgy, urban gas supply and other industries. It is the preferred product for the transmission and distribution measurement and trade measurement of natural gas in oil field and city.

3.4.1 Working power supply：
A．External power supply：＋24VDC±15%，ripple＜5％， Apply to 4～20mA output, pulse output, alarm output、RS-485 and so on； B．Internal power supply：A set of 3.6V lithium battery（ER26500）. When the voltage is lower than 3.0V, display under voltage.
3.4.2 Overall power consumption：
A．External power supply：<2W;
B．Internal power supply: average power consumption 1mW，can be used continuously for more than two years

3.4.3 Pulse output mode：
A． Pulse signal of working conditions. Amplify and output the pulse signal of working conditions that is detected by the flow sensor through photon coupled isolator directly. High level≥20V，Low level≤1V；
B． Calibration pulse signal. Matching with IC card valve controller. High level range≥2.8V，Low level range≤0.2V， The settable range of the unit pulse representative volume: 0.001m3~100m3. Must pay attention to when choosing this value：calibration pulse signal frequency should≤1000Hz;
C． Calibration pulse signals are amplified and outputted through photon coupled isolator. High level≥20V, low level≤1V.

RS－485 Communication（Photoelectric isolation），can achieve the following functions：
A．Using RS-485 interface, can be directly connected to the host computer or the secondary meter, and remote display the medium temperature, pressure, as well as the standard volume flow and the total standard volume compensated by temperature and pressure;
B．By matching the RS－485 interface with the HW－Ⅰ data collector, can form a telephone network communication system. A data collector can drive 15 flow meters;
C．By matching the RS－485 interface with the HW－Ⅱ data collector, can form a broadband network communication system. Transmit data by INTERNET. A data collector can drive 8 flow meters;

Flow meter match with data collector. Communication can be carried out by telephone line or broadband network. Read and set the historical data and parameters of each flow meter in the network. At the same time, the communication management software can achieve perfect management function.
4.4.1 Flow meter installation
When install the flow meter, no direct welding in the import and export flange, so as not to burn the internal parts of the flow meter.
Before installing the flow meter, the newly installed or repaired pipeline must be cleaned to remove the debris.
The flow meter shall be installed in the place of easy maintenance, no strong electromagnetic field interference, no strong mechanical vibration and thermal radiation effect.
The flow meter should not be used in the occasions where the flow is frequently interrupted and there is a strong pulsation flow or pressure pulsation;
When install the flow meter outdoor, there should be an upper cover to prevent the penetration of rain and sun exposure that affect the service life of the flow meter.
The flow meter can be installed in any angle, and the flow direction of the fluid should in accordance with the direction indicated on the flow meter.
In pipeline construction, should consider the installation of telescopic pipe or bellows, so as not to cause serious stretch or break to the flow meter.
The flow meter should be installed with the pipeline coaxially, and prevent sealing strip and grease enter the pipe cavity.
When use the external power supply, the flow meter must be reliable grounding. Do not use the earth wire with heavy current system jointly. In the period of pipe installation or maintenance, do not lap the earth wire of welding system with the flow meter.
In order not to affect the normal flow of fluid and easy maintenance, install bypass pipe according to the indication of figure 4. And ensure the front of the straight pipe section ≥3DN, the back of the straight pipe section ≥1DN.
4.4.2 The use and replacement of the built-in battery
battery electric power display
When the battery display the power has only one grid, the user should replace the battery within one month; when it only display the shape symbol of the battery, the battery power is depleted, and the battery must be replaced immediately.
Battery replacement method
Open the back cover of the intelligent flow totalizer, loosen the three screws on the battery cover plate, unplug the battery socket, take out the battery, and reinstall after replace the battery with a new one.
