Omega Flow Sensors and Kobold Flow Meters: Custom Industrial Monitoring Components from Silver Automation Instruments

Quick Answer: Silver Automation Instruments is a flow meter manufacturer and supplier for custom industrial monitoring components. If you are sourcing Omega flow sensors or Kobold flow meters for a replacement or plant upgrade, we can match process connections and output signals. We provide a price quote within 24 hours when you send fluid type, pipe size DN, flow range, temperature, and pressure.

Why Omega and Kobold Part Numbers Still Show Up on Plant Spec Sheets

Many industrial sites still list Omega flow sensors or Kobold flow meters on original P and ID drawings. A water treatment plant in Vietnam may run a Kobold paddle wheel sensor on a DN25 chemical dosing line. A food grade facility in Chile may use an Omega turbine sensor for CIP return flow. In practice, when one of these units fails, the local distributor often quotes 6 to 10 weeks for delivery. Most engineers skip that wait and look for a compatible flow meter supplier.

Silver Automation Instruments keeps common process connections in stock. We cover DN15, DN20, DN25, DN40, DN50, DN80, and DN100 as standard sizes. We also match pulse, 4-20 mA, 0-10 V, RS485 Modbus, and 4-20 mA HART outputs. Because most of these sensors sit on secondary lines, the replacement does not require a pipe run change.

Custom Industrial Monitoring Components That Match Existing Wiring

One common question from customers is whether they can keep the existing PLC input card. In most cases, yes. We build custom industrial monitoring components with the same output type as the old Omega or Kobold unit. Last year a chemical blending plant in Indonesia replaced a Kobold flow meter on a DN15 dosing line. The original unit sent a pulse signal to a local PLC. We supplied an oval gear flow meter with the same pulse divider and the same process connection. The plant finished the swap in one afternoon.

Before quoting, our application team checks four things:

Flow range in L/h or kg/h

Pipe size DN

Fluid viscosity in cP

Output signal and power supply

This is not a generic checklist. We use it to avoid sending a sensor that does not fit the process.

Flow Meter Options by Fluid and Process

Omega flow sensors often cover air, water, oil, and some chemicals. Kobold flow meters are common for low flow liquid and gas monitoring. We match those applications with our own instruments.

For water and wastewater lines up to DN200, electromagnetic flow meters give accuracy of ±0.5 percent of reading. They work well as a seawater flow meter for a desalination plant in Saudi Arabia and for municipal water treatment in Australia.

For diesel, heavy oil, and fuel oil, oval gear flow meters handle viscosity from 1 to 2000 cP. A fuel oil distributor in South Africa uses our DN25 oval gear meter with pulse output on its delivery skids.

For chemical dosing and low flow liquids, oval gear or ultrasonic flow meters work well. We often recommend a DN10 or DN15 oval gear meter for polymer dosing in Southeast Asia.

For compressed air and gas flow, thermal mass flow meters give mass flow directly in kg/h or Nm3/h. They are a practical replacement for Omega air flow sensors on plant utility lines.

What to Send for a Quote

Here is the thing. Most engineers send only a part number. We can work with that, but a part number alone does not tell us the fluid, temperature, pressure, or output. To avoid back and forth, send us this information:

Pipe size DN, for example DN25 or DN50

Fluid and viscosity

Flow range, for example 50 to 500 L/h

Temperature in °C

Pressure in bar

Output required, such as pulse, 4-20 mA HART, or RS485<
