PAT (Position Analog Transmitter) Shaft Encoder

by Stevens Water Monitoring Systems, Inc.     based in Portland, OREGON (USA)

The Position Analog Transmitter (PAT) is a stand-alone water level shaft encoder. The PAT is ideal for industrial and hydropower application with a 4-20 mA output. A precision potentiometer is the measuring element, and a number of ranges are available, depending on gear selection.

Model IRU5180 - Non-Contact Level Sensor

by Stevens Water Monitoring Systems, Inc.     based in Portland, OREGON (USA)

The IRU 5180 is a non-contact, solid state device for the measurement of level, volume, proximity, or distance in corrosive material environments. The IRU operates by transmitting a series of ultrasonic sound waves in a cone shaped pattern. Sound waves reflect from the target being measured back to the sensor, which measures the time interval ...

OTTCBS - Compact Bubbler System

by Stevens Water Monitoring Systems, Inc.     based in Portland, OREGON (USA)

The OTT CBS Compact Bubble Sensor is a compact, accurate, efficient, robust, and easy-to-use SDI-12 bubbler sensor for water level monitoring, which meets and exceeds US6S guidelines for accuracy. The CBS is low maintenance, with no desiccant required. A 5 year life is expected based on 1 minute intervals—no pump maintenance or lubrication ...

Contact Meter

by Stevens Water Monitoring Systems, Inc.     based in Portland, OREGON (USA)

Our contact meter is an ideal device for quick, portable measurement of bore holes, wells, reservoirs, and other applications where liquid level depth is needed. The probe is simply fed down and when it reaches liquid the light on the front of the unit illuminates. Depth can then be read from the easy-to-read white tape.

Non-Contact Sensors

by Stevens Water Monitoring Systems, Inc.     based in Portland, OREGON (USA)

Both ultrasonic and sonic level instruments operate on the basic principle of using sound waves to determine fluid level. The frequency range for ultrasonic methods is 20-200 kHz, and sonic types use a frequency of 10 kHz. A transducer directs sound waves downward in bursts onto the surface of the water Echoes of these waves return to the ...

Encoders/Floats

by Stevens Water Monitoring Systems, Inc.     based in Portland, OREGON (USA)

A shaft encoder like the Stevens PAT is an electro-mechanical device used to convert the angular position of a shaft or axle to an analog or digital electrical signal. Part of the mechanical aspect of this device for level measurement utilizes a float and counter-weight attached to a line or tape placed around a pulley attached to the encoder's ...
