Assured Automation Flow Meter: Smart Electronic LCD Display Inline Piping Probes
Quick Answer
Quick Answer: The Assured Automation flow meter smart electronic LCD display inline piping probe gives local flow reading and signal output for water, chemical, fuel, and air lines. Silver Instruments supplies compatible inline flow probes and full bore meters for DN10 to DN80 lines with 4-20 mA, pulse, or RS485 output.

What The Smart LCD Display Inline Probe Is Used For
These meters are installed directly in a pipe run. The probe body sits in the flow stream. A smart electronic LCD display shows flow rate and total volume. No separate converter is needed in most small piping systems. Process engineers use them for local flow confirmation during batching, flushing, or dosing.
Silver Instruments works with plants that already have Assured Automation probes or need a drop-in replacement. We see this often in water treatment skids, paint mixing lines, and small fuel transfer systems. The original LCD may fail after vibration or moisture ingress. A replacement probe with pulse output can restore the loop in one shift.
Key Performance Parameters
The inline probe style works best in clean liquids and low viscosity fluids. Most applications are below 50 cP. For higher viscosity or dirty media, a full bore electromagnetic or oval gear meter is a better fit. Temperature range is usually -10 to 80 °C. Pressure depends on the probe housing and process connection.
Common outputs include 4-20 mA, 0-10 V, pulse, and RS485 Modbus. Some models accept PT100 temperature input for heat meter duty. If you need digital communication, we can add HART on selected Silver Instruments flow meters. The standard output is 4-20 mA plus pulse. But many Assured Automation LCD probe replacements only need pulse for a PLC or batch controller.
Line Sizing and Materials
Do not size a flow probe by pipe diameter alone. You need minimum and maximum flow rate in liters per minute, m3/h, or kg/h. A probe in an oversized line may not spin at low flow. A probe in a small line may create high pressure drop. Most engineers skip this part because the existing meter has a known process connection.
Silver Instruments stocks inline probes with brass, stainless steel 304, stainless steel 316, and PVC bodies. Process connections include NPT thread, BSP thread, tri-clamp, and flanged ends. For seawater or chemical duty we recommend 316 stainless or PVC with no aluminum parts. In practice, a water treatment plant in Vietnam replaced plastic probe bodies every 14 months until they switched to 316 stainless.
If the installation is in a solvent storage area, ask for ATEX Zone 1 or Zone 2 certification. Explosion proof meters are available for fuel and solvent lines.

If the fluid is water, wastewater, or chemical with conductivity above 20 µS/cm, use a Silver Instruments SEF series electromagnetic flow meter. It has no moving parts. The LCD display is local and the output can be 4-20 mA, pulse, RS485, or HART. Line sizes cover DN15 to DN80 for small skids.
For diesel, fuel oil, or solvent below 50 cP, use a Silver Instruments OGF oval gear flow meter. It installs inline and provides pulse or 4-20 mA. A paint manufacturer in Thailand uses this series on solvent dosing at 0.5 to 20 L/min. For compressed air or nitrogen, a Silver Instruments STMF thermal mass flow meter works from DN15 to DN50.
Installation and Maintenance Notes
Install the probe with straight run before and after the meter. Most probe flow meters need 5 DN upstream and 3 DN downstream. Avoid mounting the LCD directly above a hot pipe. Moisture inside the display housing is the most common failure we see on customer sites. Use a drip leg or hood for outdoor installation in the Middle East or Southeast Asia.
Do not use a probe style meter for abrasive slurry. Solids can damage the rotor or probe tip. In these applications a full bore electromagnetic meter with PTFE liner and no moving parts lasts longer.
FAQ: Five Key Questions
Can this inline flow meter handle seawater?
Yes if the probe body and rotor material are 316 stainless or PVC. We do not recommend brass or aluminum for seawater lines. A desalination plant in Oman asked us for a PVC probe replacement last year.
What output should I use for a PLC?
Pulse output works for totalizing and batching. 4-20 mA is better for continuous flow rate control. RS485 Modbus is good when you need flow rate, total, and diagnostics on one bus.
What if my fluid is not water?
Tell us the density, viscosity in cP, and chemical compatibility. We can select the probe body, rotor, and seal material. Do not assume a water meter works for diesel or solvent.
Can I use a probe meter on a 3 inch pipeline?
Yes, but verify the minimum flow. DN80 is common. If the flow range is wide, a full bore electromagnetic meter may give better accuracy at low flow.
What is the lead time for a replacement probe?
Standard DN15 to DN50 probe meters ship in 5 to 10 days from our Nanjing warehouse. Special flanged or 316 stainless bodies may take 2 to 3 weeks.
