Flow meter
Thread Content
I would like to ask everyone: the water meters commonly used in ordinary households are rotary dry-type water meters. Are there any meters of this type that can measure acidic liquids?
Stainless steel water meters of types 15#–65# are multi-flow rotary vane water meters; as the original poster mentioned, those of types 80#–100# are magnetic transmission dry-type water meters. It is made of 304# stainless steel and high-strength plastic resin. It can be used for measuring clean water, as well as corrosive liquids and acidic or alkaline fluids. It is pollution-free, resistant to high pressure, and capable of withstanding acids, alkalis, and corrosion; its service life is also long
I was wondering if you could provide the manufacturer; a phone number would be great.
Most common stainless steels are not resistant to corrosion by hydrochloric acid and hydrochloric acid saline solutions, so this should be taken into account when selecting them.
The direct-reading multi-flow rotor dry-type water meter is designed based on traditional mechanical multi-flow rotor dry-type water meters, with the addition of photoelectric sensors and an intelligent communication module. This phenotype utilizes photoelectric encoding technology; the sensor is separated from the counting gear, with no mechanical contact. Sealing and waterproofing measures are applied, but the meter cannot be used in submerged environments. The actual photo of the direct-reading multi-flow rotary dry-type water meter is as follows: Technical specifications: Power supply – Supply method: Instantaneous power supply. Environmental conditions: (1) Temperature: -10ºC to +50ºC; (2) Relative humidity: 5% to 85%; (3) Atmospheric pressure: 80Kpa to 106Kpa. Communication methods: (1) Interface type: M-Bus; (2) Communication parameters: Baud rate of 2400bps, even parity, 8 data bits, 1 stop bit. Communication protocol CJ/T188-2004 \"Technical Requirements for Data Transmission of Household Metering Instruments\" ； Features: Directly reads the gauge’s window value; it is not based on cumulative pulse conversion, so there is no cumulative error. The meter is passive; there are no batteries inside it, so it consumes no power under normal conditions. The direct-reading device is powered only at the moment of reading the meter. Direct-reading meters have a unique address code, which ensures that the address is unique and correct; the address can be modified and set as needed.
