Gray iron case vertical removable flange industrial water meter
Measuring the volume of cold (hot) water passing through the pipeline.water meter is used for irrigation,municipality etc
A flange is a connecting profile that is commonly used to connect oil and gas surface equipment. A method for providing assembly and disassembly of components. Most oilfield flanges have a bolt hole pattern that secures the joint and gasket profile to ensure a sealed pressure seal.
This type of water meter can be used for a remote reading transmission system as equipped with a built-in sensor.Measuring the volume of cold (hot) water passing through the pipeline.All meters will be guaranteed against defects in workmanship and materials for a period of one (1) year from the date of acceptance.Defective meters or parts discovered within this period shall be replaced without charge upon return to the HBM Meters.
Operation mode: mechanical 、pulse output、 remote transmission RS485
Features:
1.No worm gear transmission mechanism, the impeller direct drive counter, transmission efficiency, low initial flow.
2.Wide range, suitable for large changes in traffic occasions.
3.Full flow detection, high precision measurement.
4.Dry magnetic structure, to ensure that the counter clean, clear display.
5.Six-digit increase in digital character wheel display readings, reading more clearly.
6.Removable measuring movement structure, easy maintenance.
7.Internal adjustable structure, to prevent unauthorized regulation.
8.Built-in stainless steel filter, the effective protection of measuring institutions.
9.High wear-resistant bearing system (gemstone bearing + high wear-resistant carbide shaft) ensures long-term product stability and reliability, significantly increasing product maximum flow.
10.Using stainless steel fasteners and epoxy resin powder to spray inside and outside the shell, to maximize antirust and extend product life.
11.Optional tamper protection cover. (To prevent users from unauthorized movement, damage or change the measurement structure, the maximum play anti-theft effect).
