Digital Flow Meter DN50: Two-Inch Smart Electronic Display Fluid Sensors
Quick Answer: The DN50 digital flow meter (2-inch) from Silver Automation Instruments is an inline metering device with a local electronic display, 4-20 mA, pulse, and RS485 outputs. It reliably measures conductive liquids in water treatment, chemical dosing, and HVAC systems. Send your flow range, operating pressure (bar), and pipe size to [email protected] and we will return a full specification within one working day.
What Is a DN50 Digital Flow Meter with Electronic Display?
A DN50 smart electronic display fluid sensor is typically a full-bore electromagnetic flow meter with no moving parts. You bolt it directly into a 2-inch pipe run. The built-in converter shows real-time flow rate in m3/h, gpm, or L/s on a backlit LCD. Because magmeters need a minimum conductivity (often >5 µS/cm), they are perfect for water, wastewater, brines, acids, and food products. Pure oils and deionized water will not work. Here is the thing: many plants replace old mechanical meters with this digital type because there is nothing to jam or snap.
Silver Instruments builds these meters with a PTFE or hard-rubber liner, 316L or Hastelloy electrodes, and an IP67 housing. The local display also lets you scroll through diagnostics and totalizer values without opening the terminal box. In practice, commissioning a DN50 magmeter takes less than 15 minutes once pipe flanges are aligned.
Key Specifications Engineers Care About
Nominal diameter is DN50, with flange drilling to ANSI 150 lb, JIS 10K, or EN 1092-1 PN16. Accuracy is typically ±0.5% of reading for flows above 0.5 m/s. The turndown ratio can reach 1:20 or better. Most engineers skip this part but check ground rings: if your pipe is plastic or lined, insist on grounding rings or a reference electrode.
Output choices include 4-20 mA HART, RS485 Modbus RTU, and scalable pulse. A PT100 input is available for temperature compensation when you order the ultrasonic or Coriolis version, though the standard electromagnetic sensor does not require it. Power supply options are 24 V DC or 220 V AC. For hazardous locations, Silver Automation Instruments can supply an ATEX Zone 1 or Zone 2 variant with the proper Ex marking.
Where You Will See a DN50 Electronic Flow Meter
We have seen this size on many customer sites. A paint manufacturer in Vietnam replaced a sticking turbine flow meter with our DN50 electromagnetic version and cut unplanned maintenance by 60 percent. A desalination plant in Saudi Arabia uses fourteen units on the permeate and brine lines because the 2-inch digital readout lets operators quickly confirm distribution balance. In Indonesia, a modular skid builder standardizes on DN50 with
These meters also fit compact dosing trolleys. Because the flow tube is lightweight (roughly 8 to 12 kg), two technicians can install it without lifting gear. Most engineers find the local display critical during CIP cycles in food and beverage plants: you can verify soap and rinse water flow without walking back to the control room.
Why Trust Silver Automation Instruments for This Sensor?
We are the manufacturer, not a reseller. When you ask for a DN50 digital flow meter with a particular liner, electrode material, or process connection, we assemble it in our own facility and provide a calibration certificate traceable to national standards. Delivery to Southeast Asia, Oceania, the Middle East, Africa, and Latin America typically leaves within 5 to 12 working days. Smaller distributors also appreciate that we offer private labeling and rapid after-sales support via WhatsApp or WeChat.
Five Frequently Asked Questions
Q: Can a DN50 digital flow meter handle liquids with solid particles?
A: Yes, if the particles are not ferromagnetic and the liner is polyurethane or ceramic. Abrasive slurries need a special throat diameter selection. Mention your solids content when you email [email protected].
Q: What is the minimum straight pipe run?
A: For a standard DN50 magmeter, 5 diameters upstream and 3 diameters downstream is safe. In tight spaces, a reduced straight run is possible if turbulence is low and you accept a slight accuracy shift.
Q: Does the electronic display support multiple languages?
A: The standard menu is in English, but we can preload Spanish, Portuguese, or Arabic firmware on request. Specify your language requirement with the order.
Q: Can this meter measure bidirectional flow?
A: Yes. The converter detects reverse flow and shows a minus sign on the display. Totalizers can be set to count forward only, reverse only, or net.
Q: How do I power the meter in a remote location?
A: A 24 V DC solar-compatible version is available. Tell us your battery bank voltage and we will add the right surge protection.
