Tank level indication and alarms
For local indication, consider a magnetic flag gauge or glass level gauge. For high- or low-level switching, consider a float or magnetic switch. A 531 transmitter provides a two-wire 4–20 mA signal, with optional HART; 528/529 switches provide separate alarms.

Tank and pump level control
Consider a 506 cable float where there is room for free movement, or a 500/520 configuration for fixed switching positions or multiple control points. Inlet turbulence, float clearance and maintenance access affect selection.
Pipe flow indication and signal integration
Consider the 615 for low flow, the 617 for variable-area measurement with a transmitter, electromagnetic measurement for conductive liquids, or a paddlewheel where the fluid allows reliable rotor operation. Compare range, fluid properties, pressure loss and piping conditions.

Leak monitoring for double-wall tanks and sumps
Select 586 sensors for the dry or brine-filled interstice or sump, paired with an 810 audible/visual alarm monitor. Remote relay outputs and RS-485 are optional.
Corrosive, hot or crystallizing fluids
Start with the chemical name, concentration, operating temperature and pressure, then assess wetted materials, seals and thermal requirements. A stainless-steel designation or a maximum temperature or pressure alone does not establish suitability. Contact us for application-specific support.
Planning, design and manufacturing experience across demanding applications
Chemical plants: fluid composition, concentration and interfaces
We have planned, designed and manufactured level and interface gauges for chemical plants handling a range of solvents at different concentrations. We assess wetted materials, seals, operating conditions and density changes. Interface applications also require the densities of both liquids, their density difference and any emulsion layer to be considered when specifying the float and chamber.
Tank and boiler manufacturers: instruments matched to the equipment
We plan, design and manufacture level gauges, flow instruments and leak-detection equipment for tank and boiler manufacturers working with complex operating conditions. Connections, center spacing, installation and service access are considered alongside local indication, remote signals and alarms as part of the equipment design.
Petrochemical plants: measurement at high temperature and pressure
Our experience includes level and flow instruments for high-temperature, high-pressure service in petrochemical plants. We assess the body, wetted components, connections, seals and thermal protection against the fluid and operating/design conditions. Suitability is established for the complete assembly, not from the maximum rating of an individual component.

How we help you select instruments
Define the measurement task
Clarify whether you need local indication, a continuous signal, high/low alarms or totalized flow, and whether this is a new installation or a retrofit.
Review process and installation conditions
Review the fluid, operating and design temperature and pressure, materials, connections and available space to identify the conditions that constrain selection.
Assess instruments and options
Compare suitable instrument types and check the combination of floats, wetted parts, indicators, switches and transmitters. Identify outstanding information for further discussion.
What to include in your inquiry
You do not need a model number. Send the information you already have and mark unknown details as “to be confirmed”.
| Item | Information to provide |
|---|---|
| Process fluid | Name, concentration, density/specific gravity, viscosity, and any solids, bubbles, crystallization or coating |
| Temperature and pressure | Normal, minimum and maximum operating values, plus design limits; identify gauge or absolute pressure |
| Level requirements | Measuring range, nozzle center-to-center distance, flange stand-off, nozzle inside diameter and alarm levels |
| Flow requirements | Minimum, normal and maximum flow; units and reference conditions; pipe inside diameter, flow direction and available straight runs |
| Installation and signals | Connection standard and size, wetted materials, site photos or drawings, power supply, receiving equipment and hazardous-area requirements |
Attach photos and drawings to your email to help us review connections and maintenance access.
Common planning questions
Can I add a remote signal to an existing level gauge?
First confirm the model, magnetic arrangement and available space, then assess compatible transmitters. Please provide the nameplate and installation photos; compatibility across makes or types is not guaranteed.
Is pipe size enough to select a flow meter?
We also need the fluid, flow range, temperature, pressure and installation conditions. The same pipe size can involve different velocities, pressure losses and suitable measurement methods.
