Electromagnetic flowmeters for conductive liquids: no moving parts, nothing obstructing the bore. W, P, H and L variants differ by liner, electrode and hygienic construction.

Use it whenWater, wastewater, chemicals and slurries. The default for municipal water and for dirty service where anything mechanical would wear out.

Coriolis meters, measuring true mass flow and density directly rather than inferring them from volume.

Use it whenAccuracy is the spec (custody transfer, batching and dosing), or the fluid's density shifts with temperature and a volumetric reading would lie.

Ultrasonic, inline and clamp-on. No pressure drop and no obstruction.

Use it whenYou're retrofitting a line that can't be cut or shut down. Clamp it on the outside of the existing pipe.

Thermal mass flow for gases, giving mass flow directly without separate pressure and temperature compensation.

Use it whenCompressed air, nitrogen or natural gas. Especially compressed air, where separate P and T compensation is usually where the metering goes wrong.

Vortex meters for steam, gases and low-viscosity liquids.

Use it whenSteam service, or hot and high-pressure duty where a magmeter or Coriolis isn't an option.

Hygienic filling and dosing meters.

Use it whenFood, beverage or pharmaceutical batching where the meter has to be cleanable.

Gauge and absolute pressure transmitters, in ceramic and metal-diaphragm versions.

Use it whenSpecify the ceramic cell for abrasive or corrosive media where a metal diaphragm wouldn't survive the year.

Differential pressure transmitters.

Use it whenNot just flow. It's how you measure level in a closed or pressurised tank, and how you see a filter blinding before it actually blinds.

Vibronic point-level switches, largely indifferent to density, coating and foam.

Use it whenHigh and low alarms, pump dry-run protection, overfill prevention. It survives where a float gets stuck.

Free-space radar for continuous level, non-contact.

Use it whenThe default for tanks and silos when you want no instrument in the product.

Guided-wave radar: a probe guides the signal instead of shooting it across open space.

Use it whenFree-space radar is struggling: narrow or agitated vessels, heavy foam. Also the answer for an interface, like an oil-water layer in a separator.

Submersible hydrostatic level probes.

Use it whenWells, reservoirs and water tanks. Drop it in and read the head.

Hydrostatic level with a ceramic cell.

Use it whenPastes and slurries that would clog or coat a conventional cell.

Ultrasonic level, non-contact.

Use it whenOpen channels, sumps and wet wells, at less cost than radar where the application allows it.

Capacitance point level for bulk solids, plus the switch electronics for the point-level sensors.

Use it whenDry solids in a bin or silo where you only need a full or empty signal.

Multi-channel transmitters and controllers: one platform takes pH, conductivity, oxygen and turbidity inputs.

Use it whenA panel needs several parameters and you don't want four different transmitters in it.

The digital sensor connection. Non-galvanic, so moisture and long cable runs stop degrading the signal.

Use it whenGenuinely the reason to prefer this line for analysis: calibrate a sensor on the bench, plug it in wet, and swap a pre-calibrated spare in seconds.

Conductivity, both conductive and inductive.

Use it whenGo inductive for high-concentration acids and caustics that would attack electrodes.

Turbidity and solids content.

Use it whenDrinking-water compliance, and watching clarifier and filter performance.

Dissolved oxygen, optical and amperometric.

Use it whenAeration-basin control in wastewater, and fermentation.

Orbisint, Orbipore, Ceramax and Tophit, which differ by junction and diaphragm.

Use it whenMatching a sensor to a fouling or high-solids process, where a general-purpose pH probe would blind.

RTD and thermocouple assemblies, thermowells, and the transmitters that pair with them.

Use it whenInsertion length and wake frequency matter more than the sensor element. Bring us the line size, velocity and temperature and we'll do the calculation. This is a sizing conversation, not a part-number lookup.
