Flow Measurement Sensors & Flow Rate Sensors: OEM Components for Systems Integration

Quick Answer: Silver Instruments supplies flow measurement sensors and flow rate sensors as OEM components for skids, analyzers, and dosing systems. Most projects match DN15 to DN300 lines with 4-20 mA HART, pulse, or Modbus outputs. Send your fluid, flow range, pressure, temperature, and pipe size for a direct quote.

Systems integrators in Southeast Asia, the Middle East, and Latin America install these sensors inside packaged plants. The sensor has to fit the pipe, output the right signal, and survive the process. A Coriolis sensor on a palm oil blending skid is not the same as an electromagnetic sensor on a seawater reverse osmosis line. We ship from China with full documentation for OEM panel builders and skid fabricators.

What OEM System Integrators Specify First

Most engineers skip the theory and go straight to four variables. Pipe size is the first factor. A DN15 oval gear sensor cannot handle a DN200 cooling water header. Fluid type is the second factor. Conductive water suits an electromagnetic sensor. Viscous oil suits an oval gear or Coriolis sensor. Output signal is the third factor. Your PLC or remote terminal unit needs 4-20 mA, pulse, or Modbus. Process limits like temperature in °C and pressure in bar decide the body material and liner.

Sensor Types and Recommended Models

For low flow liquid dosing from 0.05 kg/h to 500 kg/h, use a Silver Instruments SIL-OG-025 oval gear sensor. It handles 0.5 to 200 cP without losing pulse accuracy. For conductive water and wastewater from DN15 to DN300, use the SIL-MAG-050 electromagnetic flow sensor with PTFE liner and 316L electrodes. For high viscosity, high pressure, or mass measurement, use the SIL-CMF-025 Coriolis mass flow sensor. It reports kg/h, density, and temperature over one 4-20 mA HART loop. For gas and compressed air injection, use the SIL-TMF-015 thermal mass sensor with a range of 0 to 50 m/s. For steam and saturated vapor, use the SIL-VS-080 vortex sensor with temperature compensation built in.

Output Signals for OEM Systems Integration

Most OEM machines need a signal that connects directly to a PLC input. Our sensors come with 4-20 mA, 0 to 5 V, pulse, RS485 Modbus RTU, or HART. A water treatment skid builder in the Philippines asked for pulse output to count batch volume. A chemical dosing OEM in Chile needed Modbus because the panel already used a PLC. In practice, you can order one sensor with two outputs. You do not need a separate converter. That saves space in a control cabinet.

Installation Factors That Change Accuracy

Here is the thing. Flow sensors need correct installation. You need a straight run upstream. For a vortex sensor on a DN80 steam line, keep 15D upstream and 5D downstream. For electromagnetic sensors, make sure the pipe stays full. For oval gear sensors, install a strainer upstream to catch weld slag. We have seen customer sites in Vietnam where a missing strainer destroyed the gears within two weeks. So we always recommend a strainer on oval gear installations. In desalination plants, use 316L or titanium electrodes. In food and beverage, use tri clamp or sanitary connections and FDA approved materials.
