365Level Transmitters,UltrasonicLEVELULTRASONIC LEVEL SENSORNon-Contact Transmitter, SPST Programmable RelaysThe SERIES ULSS Ultrasonic Level Sensors provides non-contact, continuous ultrasonic level measurement of fluids for short range applications. It has a 4.1´ (1.2 m) measuring range with a 0.125˝ (3 mm) accuracy. The SERIES ULSM Ultrasonic Level Sensors provides non-contact, continuous ultrasonic level measurement of fluids for medium range applications. It has a 9.8´ (3 m) measuring range with a ±0.2% of range accuracy. The SERIES ULSL Ultrasonic Level Sensors provides non-contact, continuous ultrasonic level measurement of fluids for tall range applications. It has a 18´ (5.5 m) measuring range with a ±0.2% of range accuracy. FEATURES/BENEFITS• Via free software, units can be programmed to transmit an output signal and operate four relays for control applications• Provides reliable, accurate, and non-contact level measurement of compatible liquids• Non-contact technology offers no moving parts to wear, jam, corrode, or get coated like contact technologies• Mapping software makes effective measuring surface only a 3˝ (76.2 mm) diameter column with no concerns of ladders, pipes, or other tank intrusions in the remaining sound cone• Ultrasonic technology paired with automatic temperature compensation provides accurate and reliable measurements in almost all conditions• Fail-safe logic is easily configured to custom applications via free software removing the need for target calibration• Full NEMA 6P submersible enclosure rating to ensure excellent product durability APPLICATIONS• Water and wastewater• Pulp and paper processing • Sump and process tanks• Chemical processing • Food and beverage4´[1.2 m]3-1/4[82.55]2[50.85]ULSS-10:1˝ NPTSPECIFICATIONSService: Compatible fluids.Wetted Materials: Sensor: PVDF; O-ring: FKM.Ranges: See chart.Accuracy: ULSS: 0.125˝ (3 mm); ULSM & ULSL: ±0.2% of range.Resolution: ULSS: 0.019˝ (0.5 mm); ULSM: 0.039˝ (1 mm); ULSL: 0.079˝ (2 mm).Blind Zone: ULSS: 2˝ (5 cm); ULSM: 4˝ (10 cm); ULSL: 8˝ (20 cm).Beam Width: ULSS & ULSM: 2˝ (5 cm); ULSL: 3˝ (7.62 cm).Temperature Limits: Process: 20 to 140°F (-7 to 60°C); Ambient: -31 to 140°F (-35 to 60°C).Temperature Compensation: Automatic.Pressure Limit: 30 psi (2 bar).Power Requirement: 12 to 28 VDC.Output Signal: 4 to 20 mA, 2-wire; Invert: 4 to 20 mA or 20 to 4 mA; Fail-safe: 4 mA, 20 mA, 21 mA, 22 mA, or hold last.Loop Resistance: 400 Ω max.Electrical Connections: 4´ (1.2 m) 9 conductor shielded cable.Contact Type: 4 SPST relays.Contact Rating: 1 A max @ 28 VDC max.Deadband: Selectable (no hysteresis, 1/4˝, 1/2˝, 1˝, 1/2 cm, 1 cm, 2 cm, 5 cm or not available).Process Connection: 1˝ NPT, 1˝ BSPP (optional).Enclosure Rating: NEMA 6P (IP68).Enclosure Material: Polycarbonate; Gland: TPE.Mounting Orientation: Vertical.Memory: Non-volatile.Failsafe: Contact: Power loss: Holds last contact; Power on: Open, close, or last contact.Programming: Free PC software download (USB adapter required).Weight: 1 lb (0.45 kg).Agency Approvals: CE.4´[1.2 m]2-45/64[68.66]1-11/64[29.90]3-5/64[78.18]ULSM-10:1˝ NPTULSSULSMULSL4´[1.2 m]1-5/64[27.30]1-1/16[27.10]2-43/64[68.05]2-45/64[68.67]3-5/64[78.18]ULSL-10:2˝ NPTSERIES ULSS, ULSM & ULSL®VIDEO ONLINEDWYER INSTRUMENTS, INC. | www.dwyer-inst.comMODEL CHARTModelRangeULSS-10ULSM-10ULSL-104.1´ (1.25 m)9.8´ (3 m)18´ (5.5 m)Note: USB adapter necessary for calibration.
