Ultrasonic Level Sensor for Mud Pits, Tanks & Sewage | Non-Contact | CNPS

The sensor continuously measures the level of liquids and solids without contacting the medium, using ultrasonic sensing with built-in temperature compensation and advanced signal filtering. It outputs a 4-20 mA analog industrial signal for direct connection to control systems, and is available in an intrinsic safety / explosion-proof certified version suitable for hazardous areas.

• Non-contact ultrasonic measurement with no moving parts — Extremely low maintenance cost and long service life with fewer service interruptions.
• Measurement range 0.25 - 5.00 m (mud logging model) — Covers mud pit and tank level monitoring; model-dependent ranges extend further (confirm by model).
• Accuracy ±0.5% of full scale — Dependable level data for inventory and safety decisions.
• Built-in temperature compensation and advanced signal filtering — Stable, accurate readings even with dust, steam, foam, and turbulence.
• Wide operating temperature -40°C to +60°C, humidity resistance 5-95% RH — Rated for outdoor industrial and municipal environments.
• IP67 protection rating — Robust housing and corrosion-resistant materials for chemical tanks and silos.
• Quick installation with just a few tools — Simply align the sensor above the mud pit or tank and install.
• Intrinsic safety / explosion-proof certified models (as documented) — Suitable for hazardous areas such as volatile drilling sites.

Summary: The sensor is mounted above the medium - such as a mud pit, storage tank, or open channel - and measures level without any contact with the liquid or solid. Built-in temperature compensation and advanced signal filtering maintain accuracy even when dust, steam, or foam interfere with the measurement environment.

Steps

• Mount the sensor above the medium using just a few tools, aligned over the mud pit, tank, or channel.
• Ultrasonic signals are transmitted toward the medium surface and the reflected signal is processed to determine the level, with no contact with the medium.
• Built-in temperature compensation corrects for environmental temperature effects.
• Advanced signal filtering suppresses errors caused by foam, steam, and turbulence.
• A 4-20 mA analog output delivers continuous level data to the control system or mud logging equipment.

• Mud logging - mud pit level monitoring — Product listed as 'CNPS Ultrasonic Level Sensor (Mud Logging)' for continuous pit level tracking.
• Drilling operations — Stable level data helps operators prevent overflow, slurry loss, and equipment shutdown.
• Sewage treatment — Precise non-contact level measurements for sewage tanks and open channels; stable operation of municipal sewage treatment plants.
• Chemical storage tanks and silos — Overflow and leakage prevention with sturdy, corrosion-resistant construction.
• Industrial, municipal, and warehousing applications — Level measurement for liquids, bulk solids, and wastewater.
