A:
Submersible transmitters are a strong choice in wells, sumps, and lift stations where side or top nozzles are limited and level is best sensed from below. For harsh water and wastewater environments, a cage-protected design helps keep the sensing diaphragm safe from debris, slurry and sludge.
A:
For suction protection, place a point level device just above the minimum safe liquid height and use a continuous transmitter to control normal start/stop levels. For transfer or filling applications, a high level switch near the top of the vessel provides a hard overfill limit that backs up the continuous level signal.
A:
A cage-protected version surrounds the sensing diaphragm with a perforated guard, deflecting rocks, rags, and heavy solids while still allowing pressure transmission. This style is particularly well suited for sludge tanks, storm canals, and municipal lift stations where unprotected sensors can be easily damaged.
A:
Hydrostatic transmitters are ideal for continuous level measurement in wells, lift stations, and tanks where the media is relatively clean. Vibrating fork switches are excellent for high or low point-level protection and pump run-dry protection when you need simple binary level alarms. Radar level transmitters provide continuous, non-contact level measurement that excels in applications with varying dielectric properties, agitation, or where you want to avoid any wetted sensor in the tank.
A: NOSHOK pressure, level, and temperature transmitters provide standard analog outputs (such as 4–20 mA and voltage) and optional digital protocols like IO-Link or HART®, which connect directly to PLC input cards and remote I/O modules. The PLC uses these signals to run pump and valve logic locally, while the same data is passed up to the SCADA system for trending, alarming, and remote visibility across lift stations, reservoirs, chemical feed skids, and treatment trains making NOSHOK devices the measurement layer that feeds your plant and system wide automation.
A: NOSHOK transmitters and switches use industry standard signal types - most commonly 4–20 mA and voltage outputs, with optional HART® or IO-Link - so they connect to typical PLC analog input cards and IO-Link masters without special hardware. To ensure compatibility, confirm that your PLC has matching input types and ranges, reserve the correct I/O channels, and follow the wiring and scaling recommendations in both the PLC manual and NOSHOK data sheets; once the PLC is reading the signal correctly, your SCADA system simply tags those PLC points for alarming, trending, and remote monitoring.
A: Sodium hypochlorite is highly corrosive to many metals, so a PTFE- or polymer-based diaphragm seal isolates the instrument from attack while maintaining accurate pressure transmission. NOSHOK's all non-metallic Type 5 diaphragm seal provides a corrosion-resistant, proven solution for hypochlorite and other aggressive disinfectants.
A: Placement should reflect how the process operates: level in wet wells, reservoirs, and basins; suction and discharge pressure on pumps; differential pressure across filters and membranes. Instruments should be located where they see the true process conditions and can be wired cleanly back to PLC panels or remote I/O for control.
A: In high solids wet wells, the large, non-fouling sensing area and rugged cage of a NOSHOK 613 Series submersible level transmitter protect the diaphragm from debris and impact. This design provides stable, long-term level measurement in sewage, stormwater, and slurry environments where unprotected probes are prone to plugging and damage.
A: Continuous electronic level signals from radar or submersible transmitters feed the control panel or SCADA system, where level alarms and pump sequences can be automated. NOSHOK's intrinsically safe and cage-protected submersible level transmitters provide reliable measurement that alert operators to blockages, backups, and flooding before overflows occur.
A: Flow-through annular seals let the process media pass through a sleeve-style diaphragm, isolating the instrument from plugging while still transmitting pressure. In sludge, slurry, and polymer service, NOSHOK flow-through seals keep sensing elements clean and responsive, extending maintenance intervals and improving pump protection and process visibility.
A: Mounting a pressure gauge or electronic transmitter/switch on a flow-through annular style diaphragm seal creates a non-clogging measurement point that resists solids and buildup. This assembly ensures reliable discharge pressure feedback for pump protection, VFD control, and performance monitoring without repeated purging or line cleaning.
A: For large reservoirs and towers, NOSHOK non-contact radar level transmitters provide continuous level data without contacting the water, minimizing maintenance and contamination risk. Submersible transmitters can be used in wells and standpipes to track drawdown and recharge, supplying accurate data for storage management and distribution pressure control.
A: Submersible and cage-protected level transmitters installed in overflow tanks and detention basins deliver real-time level signals to automate valve and pump operation during heavy rain events. This data allows municipalities to coordinate controlled releases, protect downstream infrastructure, and reduce the risk of untreated discharges.
A: Installing differential pressure transmitters or gauges on filter inlet and outlet lines provides accurate differential pressure information that reveals loading and fouling trends. Operators can schedule backwashing or cartridge changes based on real data rather than time alone, protecting equipment and maintaining throughput in clarifiers, sand filters, and membrane systems.
A: Application-focused assemblies - such as non-metallic seal/transmitter packages for chemical feed or distribution manifolds feeding multiple instruments from a single diaphragm seal - create repeatable building blocks you can deploy plant-wide. This approach simplifies design and maintenance, reduces leak paths and configuration variants, and ensures consistent performance from chemical rooms and pump stations to digesters, filters, and reservoirs.
A: Look for IP65–IP68 or NEMA-rated housings, UV-resistant cables, and corrosion-resistant materials such as 316 Stainless Steel, PVDF, or Polyurethane in exposed locations. NOSHOK's submersible level transmitters and industrial transmitters are designed for immersion, wash-down, and harsh atmospheres commonly found in lift stations, headworks, and chemical feed rooms.
A: Depending on location and application, plants may require CSA or FM hazardous location approvals for instruments in classified areas, and AWWA or NSF-related requirements for materials in contact with potable water. Operators and integrators often also follow ISA and NEC electrical codes, and use vendor documentation (calibration certificates, material traceability) to support regulatory and audit requirements.
A: IO-Link is a point-to-point digital protocol that runs over standard sensor cables and provides rich diagnostics, parameterization, and process data from smart devices. In treatment plants and booster stations, IO-Link enabled transmitters and transmitter/switches give engineers more insight into device status and allow standardized configuration across multiple skids and panels.
A: NOSHOK works with municipalities, engineers, and OEMs to define application-focused packages - combining pressure, level and temperature transmitters, gauges, seals, valves, and accessories that are engineered for water and wastewater service. This reduces design time and integration risk while ensuring your instrumentation will tie cleanly into existing infrastructure, PLC programs, and SCADA standards across the facility.
