Flow Meter Nước: Thiết Bị Đo Lưu Lượng Nước Chính Hãng
Quick Answer: Silver Automation Instruments delivers genuine inline and clamp-on flow meters for clean water, wastewater, raw river water, and brine. You get factory-calibrated devices with 4-20 mA HART, Modbus RTU, or pulse output. Typical accuracy reaches ±0.2% of reading for electromagnetic meters and ±0.5% for clamp-on ultrasonic meters, and we ship every unit with a 24-month warranty and a calibration certificate traceable to Vietnamese metrology centers.
Why a Chính Hãng Water Flow Meter Matters for Your Process
Most engineers learn this the hard way. A cheap unbranded flow meter with poor electrode material fails in three months on a Hanoi groundwater line because the water carries sand and pH swings between 5.8 and 7.2. A genuine Electromagnetic flow meter uses Hastelloy C-276 electrodes and a PTFE liner, so it handles abrasive particles and mild acidity without drift. We stock DN15 to DN400 electromagnetic meters with those exact wetted materials. No mixing, no guesswork.
Chọn Đúng Loại: Which Technology Fits Your Water Line
Water is not just water. A long-distance raw water transfer main in Bình Dương needs a battery-powered electromagnetic meter with a GSM data logger. A chemical dosing skid feeding PAC into a settling tank needs a small-bore Coriolis mass flow meter because the coagulant density changes with temperature. A secondary effluent discharge pipe in a seafood processing plant in Kiên Giang needs a clamp-on ultrasonic meter to avoid cutting the pipe and dealing with the local environmental inspectors. We ship all three types from our Nanjing calibration lab, with typical lead times of 5-7 working days to HCM City or Đà Nẵng via FedEx or DHL.
Electromagnetic Flow Meters for Conductive Water: DN15 to DN400
If your water has a conductivity above 20 µS/cm, this is the tool. Our SMag series uses a remote-mounted converter with backlit LCD and three totalizers. The empty pipe detection function saved a district metered area project in Manila last year: the log showed zero flow at 2 a.m. but the 4-20 mA still looped 4.00 mA, so the SCADA operator knew the pipe ran dry, not a broken signal. Standard flange ratings go from PN10 to PN40, and we supply the matching grounding rings. Just tell us your pipe material, whether it is steel or HDPE, and we will include the right grounding electrode or ring.
Clamp-on Ultrasonic Meters: No Pipe Cutting, No Downtime
In practice, clamp-on meters save you one full maintenance shift. We installed an SUL series clamp-on on a 12-inch cement-lined ductile iron pipe at a Đồng Nai water treatment plant. The pipe ran 24/7, so a tie-in was not allowed. The transducer pair mounted with stainless straps and acoustic coupling gel in under 40 minutes. The meter shipped with a wall-mount converter, 4-20 mA output, and Modbus RS485 configured to slave ID 1, baud rate 9600, no parity. Accuracy on that job held ±1.0% of reading, confirmed by a six-month comparison against the plant reservoir level change. We recommend sending us your outer pipe diameter, wall thickness, and material, so we can pre-select the correct transducer frequency, usually 1 MHz for DN100 and up, 2 MHz for smaller lines.
Coriolis Mass Flow Meters for Water-Based Chemicals and Additives
When you dose sodium hypochlorite or caustic soda, volume measurement is not enough. A 10% NaOH solution at 25°C weighs 1.11 kg/L. At 35°C i
Oval Gear Meters for Clean Water Batching and Truck Loading
Here is the thing about batching demineralized water for a pharmaceutical mixing tank. The conductivity is below 0.5 µS/cm, so a magnetic meter does not work. An oval gear flow meter with PPS gears and ceramic bearings fills a 200-liter vessel in 90 seconds with ±0.5% repeatability. Our SOG series comes in 1/2-inch and 3/4-inch connections, with a local register totalizer and a Reed switch pulse output. One customer in a printing ink factory near Bắc Ninh uses the same meter to measure solvent, water, and a low-viscosity resin on three separate lines. They swap just the seal material, from Viton to PTFE, nothing else.
Sizing and Ordering: What We Ask From You
The fastest way to a correct quote is sending us five numbers. Pipe inside diameter in mm, normal flow in m³/h, maximum flow, pressure in bar, and water temperature in °C. If the water is chlorinated, let us know the free chlorine level in mg/L. For abrasive water with silt, share your typical NTU or mg/L of suspended solids. Our engineers pick the liner, electrode, and grounding method from that data. We answer technical inquiries within 12 hours during Vietnamese business hours via email [email protected], Tel +86-135-1213-1526, or WhatsApp 86-135-12131526. You can also reach us on WeChat at +86 13512131526. When you email, attach a photo of your pipe or your current meter nameplate, if possible. It speeds up the identification by half a day.
FAQ Section
1. What is the minimum conductivity for your electromagnetic flow meters? Our standard SMag series works reliably above 20 µS/cm. Below that, for demineralized or RO permeate water, we recommend a Coriolis or ultrasonic meter instead.
2. Can I use a clamp-on ultrasonic meter on old cement-lined steel pipe? Yes, but the liner must be bonded tightly. We ask for the outer diameter and wall thickness including the lining, then run an acoustic coupling test signal. Often we select a 0.5 MHz transducer for better penetration.
3. Do you supply calibration certificates recognized in Vietnam? Every meter leaves our factory with a 5-point calibration certificate. The report references master meters traceable to national standards, and Vietnamese quality inspectors have accepted these for industrial permits.
4. What is the lead time for a DN80 electromagnetic flow meter with PTFE liner and Hastelloy electrodes? If we stock the sensor, usually 3-5 working days to your forwarder. Custom liners or exotic materials add 10-14 days. We keep popular DN80 and DN100 models in inventory for quick dispatch.
5. Does Silver Instruments offer on-site commissioning in Vietnam? We normally support remotely via video call or our local distributor engineer. We walk your team through the wiring, zeroing, and configuration steps using a mobile camera. Most start-ups finish in under an hour.
