BOQU 4 20ma ,modbus digital output electromagnetic water flow meter

Premium Water Magnetic Electromagnetic Flow Meter

Magnetic flow meters are often selected because they are obstructionless, cost-effective for aggressive chemicals,slurries,wastewater applications or any dirty liquid which is conductive or water based and provide highly accurate volumetric flow measurement. A range of liner materials, electrode options and line sizes accommodate a wide variety of process applications. Additionally, magnetic meters are beneficial in that they can measure fluids bi-directionally, are effective for both very low and high volume flow rates and are immune to changes in process variables. Magnetic flow meters are also ideal for applications where low-pressure drop and low maintenance are required.

Product Description

Features of water hose flow meter

1) Measurement is not affected by the variation of flow density, viscosity, temperature, pressure.
2) High accuracy measurement is guaranteed according to the linear measurement principle.
3) No moving in the pipe, no pressure-loss and lower requirement for straight pipeline.
4) DN 6 to DN2000 covers a wide range of pipe size.

5) A variety of liners and electrodes are available to satisfy different flow characteristic.
6) Measurement stability and reducing power consumption.
7) Implementing 16 bits MCU, providing high integration and accuracy;

8) Full-digital processing, high noise resistance and reliable measurement;

9) Flow measurement range up to 1500:1.
10) High definition LCD display with backlight.
11) RS485 or RS232 and Wireless Function
12) SMD component and surface mount technology (SMT) are implemented to improve the reliability.

Applications of water hose flow meter:  water, wastewater, mining, mineral processing, power, pulp and paper, and chemical industries. Food, beverage, pharmaceutical, cooling water, metals processing, fertilizers, inorganic chemicals fertilizers ,soda , aqueous acid solutions,aqueous alkaline solutions, polymer chemicals, water-soluble adhesives, liquid containing solid matters, concrete slurries, mortar, slurry of solid matter, Water and wastewater applications include custody transfer of liquids in force mains between water/wastewater districts. Magnetic flowmeters are used in water treatment plants to measure treated and untreated sewage, process water, water and chemicals. Mining and mineral process industry applications include process water and process slurry flows and heavy media flows.

How to select right water hose flow meter ?
The key questions which need to be answered before selecting a magnetic flow meter are:
Is the fluid conductive or water based?
Is the fluid or slurry abrasive?
Do you require an integral display or remote display?
Do you require an analog output?
What is the minimum and maximum flow rate for the flow meter?
What is the minimum and maximum process pressure?
What is the minimum and maximum process temperature?
Is the fluid chemically compatible with the flow meter wetted parts?
What is the size of the pipe?
Is the pipe always full? 


BOQU was found since 2007, now has more 70 staff and engineers, instruments has be exported to over 75 countires.,Now BOQU has been named as High-Tech Enterprice by goverment,ISO,CE, SGS is our common certicates. the core technology of electrode ,controller and 50+ software property is our based. all instruments has been recognized by National Metrology Bureau.there is many small factories in China, you should be carefully if they provide you very low price. this is tips for you in free.
