1/2 Inch Water Flow Meter: 0.5 Inch Inline Digital LCD Volumetric Gauges for DN15 Lines
Quick Answer: The 0.5 inch inline digital LCD water flow meter is a volumetric gauge for DN15 water lines. It reads flow rate and total volume directly on the meter body. Send your flow range in L/min, thread standard, pressure in bar, and temperature in °C to Silver Automation Instruments for a same-day quote.
What the 0.5 Inch Digital Water Meter Does
This meter installs directly in a 0.5 inch pipe. The local LCD shows flow rate and accumulated total. Operators read batch volume without a PLC or control cabinet. The unit suits clean water, RO permeate, cooling water, and low viscosity liquid.
Typical installations include reverse osmosis skids, cooling water return lines, washdown stations, boiler feed water lines, and irrigation test loops. We supply users in Vietnam, Indonesia, Saudi Arabia, Chile, and Australia. Most buyers replace a mechanical paddle wheel meter or a rotameter with this digital gauge.
Technical Specifications to Check Before You Buy
Pipe size: DN15, 0.5 inch BSP or NPT thread
Flow range: 0.5 to 30 L/min for water, equal to 30 to 1800 kg/h at 20 °C
Accuracy: ±2% of reading from 1 to 30 L/min
Wetted parts: brass or POM body with EPDM or FKM seals
Local display: 4 digit LCD with flow rate and total volume
Power: 3 V lithium battery or 12 to 24 VDC
Output: pulse output standard, 4-20 mA HART optional
Pressure: 10 bar maximum at 25 °C
Temperature: 0 to 60 °C, no PT100 needed for clean water
Optional: ATEX Zone 1 approval for the 4-20 mA transmitter type
In practice, most engineers skip the battery version for outdoor skids. They choose 12 to 24 VDC power and a 4-20 mA signal. This feeds the site PLC or a local panel. The pulse output works well for totalizing in a batch controller.
Installation Advice for DN15 Water Meters
Keep a straight run of 5 DN upstream and 3 DN downstream. This reduces swirl and gives a stable reading. The meter tube must stay full of water. Do not install the meter at the top of a pipe with air pockets. A Y strainer upstream prevents sand or plastic particles from damaging the rotor.
We have seen this on customer sites many times. A water treatment contractor in Indonesia installed 12 units on chemical dosing skids. The LCD allowed

Model Selection and Quote Details
The Silver Instruments WM-015L digital water meter covers DN15 water lines with 0.5 inch threads. For aggressive water or chemical dosing, request the POM body and FKM seal. For clean water, the brass body version costs less and works well.

FAQ: 1/2 Inch Digital Water Flow Meter
What is the difference between 0.5 inch and DN15?
0.5 inch is the imperial pipe size. DN15 is the same nominal bore in metric terms. The meter body accepts both naming conventions. Confirm the thread standard before ordering because BSP and NPT threads differ.
Can this meter measure water with low conductivity?
Yes. This volumetric gauge does not need conductive liquid. An electromagnetic flow meter often needs conductivity above 20 µS/cm. This digital gauge works for RO permeate and demineralized water.
What is the minimum flow the meter can detect?
The typical minimum flow is 0.5 L/min for clean water. Below this value the rotor may not turn consistently. If you need lower flow, send us your minimum and maximum flow in L/min. We can check a smaller meter or a different technology.
Can I use this meter for diesel or chemicals?
The standard water meter is for water. For diesel, fuel, or high viscosity fluids above 50 cP, an oval gear flow meter is more stable. For low viscosity chemicals, confirm wetted material compatibility with our engineers before ordering.
Does the LCD display total volume only or flow rate as well?
The LCD shows both. Most users toggle between instantaneous flow rate and accumulated total. The total can be reset on some models. Ask us for the reset function if you need batch control.
