2 Flow Meter with Totalizer: Inline Smart LCD Digital Volume Counters
Quick Answer: This is a DN50 inline flow meter with a built-in totalizer. The smart LCD shows flow rate and total volume at the same time. Silver Automation Instruments supplies this meter for water, diesel, chemicals, and food liquids, with 4-20 mA output, pulse output, and optional RS485 Modbus.
What This Flow Meter Does
The meter is not a simple flow switch. It measures flow and adds volume to a totalizer. The LCD display gives two numbers at once: flow rate and accumulated volume. Operators use the totalizer for daily production, water intake, chemical dosing, and fuel transfer records. The totalizer can be reset locally or protected for plant auditing.
Why DN50 and 2 Inch Size Matters
DN50 is a common pipe size in small and medium plants. The 2 inch connection fits many transfer lines, filter skids, and wash water loops. You can choose flanged, threaded, or tri-clamp ends. Flanged connections are common in water plants. Tri-clamp is common in food and beverage lines. In practice, if your line is DN40 or DN50, our engineers will check the flow range before confirming the 2 inch model.
Technical Parameters for the Inline Digital Meter
Flow range is 0.4 to 40 cubic meters per hour for water-like liquids. Accuracy is plus or minus 0.5 percent of full scale. The display is a two line smart LCD. Outputs are 4-20 mA, pulse, and optional Modbus RS485. Power supply is 24 VDC standard. Wetted parts are 304 stainless steel or 316L for aggressive liquids. Process pressure rating is PN16 or ANSI 150 lb as standard. Protection is IP65 or IP67 depending on the housing.
Applications We See on Customer Sites
A water treatment contractor in the Philippines uses this meter on a reverse osmosis skid. The pulse output sends total volume to a PLC. A juice bottler in Thailand uses the 2 inch totalizer meter with 316L wetted parts for filtered water batches. A diesel generator supplier in Nigeria uses an oval gear version for fuel transfer from day tanks. A paint manufacturer in Vietnam uses a chemical-resistant version to monitor solvent transfer. Each application has different fluid data. We use that data to select the right meter type.
Installation and Wiring Notes
Mount the meter in a straight pipe section. Keep 10D upstream and 5D downstream if your datasheet asks for it. Avoid air slugs. Install a strainer if the

Why Buy from Silver Automation Instruments
We carry standard DN50 inline totalizer flow meters in our factory warehouse. Common water models ship within 7 days. Custom models for fuel, seawater, or chemical service take 10 to 15 days. You get a calibration certificate, an English manual, and direct technical support by phone, WhatsApp, or WeChat. We sell to distributors and end users. We do not require a large minimum order for the first trial unit.
FAQ
Can this 2 flow meter show both flow rate and total volume? Yes. The smart LCD has two lines. One line shows instantaneous flow. The other line shows total volume. You can reset the total locally or keep a permanent total.
What is the difference between 2 inch and DN50? They refer to the same nominal pipe size. 2 inch is the imperial name. DN50 is the metric name. Confirm the flange standard and pressure class before ordering.
Which output is best for a PLC? Choose pulse output for volume counting. Choose 4-20 mA for flow rate trending. Choose RS485 Modbus if your PLC needs both values and diagnostics on one bus.
Can this meter handle seawater? Yes, if you select the electromagnetic or ultrasonic version with 316L electrodes and a suitable liner. Send us the salinity and temperature so we can confirm the liner material.
What maintenance does this meter need? For clean water, maintenance is low. For dirty or sticky liquids, clean the sensor or strainer monthly. Check the display window and cable glands every quarter.
