Supported Applications
The Omega LV-40 and LV-50 series are vertical mount liquid level switches constructed of 316 SS for chemical resistance. The product overview identifies these units as suitable for rough or corrosive liquids, water-purifying applications, and medical uses. The LV-50 series is further described in the source documentation as ideal for chemical plants and systems requiring higher pressure and temperature ratings.
Operating Conditions & Performance
The series operates across distinct performance envelopes depending on the model family. The LV-40 supports an operating process temperature of -40 to 149°C (-40 to 300°F) with a pressure rating of 100 psi. The LV-50 Series handles pressures up to 750 psi and temperatures from -40 to 149°C (-40 to 300°F). A specific variant, the LV-52, extends the temperature capability to -40 to 249°C (-40 to 480°F) while maintaining a pressure rating of 750 psi. All models feature an SPST switch with actuation occurring at approximately half the distance from the end of the stem to mounting or at the halfway point of float travel.
Switch ratings vary by model: LV-40 is rated for 10 VA; LV-50 and LV-52 are rated for 20 VA; and LV-51 is rated for 100 VA. The switches support resistive loads up to the specified voltages (e.g., 0–30 V, 120 V, 240 V) with corresponding amp limits detailed in the switch ratings table.
Configuration Options
The series offers configurable options for mounting orientation and electrical switching logic. Units can be mounted vertically at the top or bottom of a tank. The switch is user-selectable as normally open (N.O.) or normally closed (N.C.) in dry conditions by removing the retaining clip and inverting the float position without disturbing installation.
Key configurable dimensions and materials include:
- Housing & Wetted Materials: 316 SS stem, float, and housing for all models.
- Process Connections: The LV-40 utilizes a mounting connection of ½ NPT (per data sheet) or 1/8" NPT (per manual); the LV-50 Series uses ¼ NPT. Note: Document sources contain conflicting values for the LV-40 process connection size.
- Dimensions: The LV-40 has an overall height of 2⅜" and a diameter of 1¼"; the LV-50 has an overall height of 3⅜" and a diameter of 2⅜". Alternative dimension sets in the manual list LV-40 as 1-1/2" diameter with a 2-3/4" stem length.
- Lead Wires: Standard leads are 22 AWG, 24" polymeric for LV-40; 18 AWG, 24" polymeric for the LV-50 Series.
The series supports operation inclined up to 30°. For switching higher current levels or pump up/pump down operations with two level switches, external solid state relays are recommended. Specific gravity requirements dictate adding 0.1 to float specific gravity for clean liquids and 0.3 for dirty water or viscous liquids.
Key Product Differences
The LV-40 and LV-50 series differ primarily in pressure capacity, temperature limits (for the LV-52 variant), physical size, and switch ratings. The LV-40 is a compact unit rated for 100 psi and up to 300°F with a 10 VA switch rating. The LV-50 Series provides superior performance with larger float displacement, handling pressures up to 750 psi and temperatures up to 300°F (or 480°F for the LV-52 model) with higher switch ratings of 20 VA or 100 VA depending on the specific sub-model.
