SUP-ZP Ultrasonic level transmitter

Product catalog summary

Overview
The document is a datasheet for the SUP-ZP Ultrasonic Level Sensor, a non-contact, easy-to-install measurement device suitable for various applications, including commercial production and aerospace industries. It is designed for high accuracy and versatility.

Features

Non-contact measurement unaffected by material properties like pressure, viscosity, and specific gravity.
Integrated keypad with security code for easy programming.
Low operating costs and maintenance-free.
Fully isolated analog 4-20mA output for better accuracy and stability.
Internal temperature compensation for improved accuracy.

Main Functions

Level measurement
Distance measurement
Volume measurement
Pump control

Operating Principle
The sensor uses ultrasonic pulses transmitted by a transducer to measure the distance to a surface. The time between transmission and reception of the pulses is proportional to the distance. The formula used is D = V*T/2, where D is the distance, V is the velocity of sound, and T is the time period.

Applications

Sewage, wastewater, and tap water treatment equipment.
Measurement of liquids like edible oils, sauces, and beverages.
Chemical materials such as solvents, paints, and slurries.
Granular materials like flour, wheat, and corn.
Petrochemical materials such as plastic powders and granules.

Technical Specifications

Measurement Range: 5 to 30 meters
Blind Zone: Less than 0.4-1.8 meters
Accuracy: 0.3% Full Scale
Display: OLED with 1mm resolution
Frequency: 20 to 350 KHz
Power: 12-24VDC or 220VAC
Output Options: 4-20mA, 1-5V, 1-10V, RS485, 2 NPN, 2 relays
Material: ABS
Ingress Protection: IP65 (IP68 optional)

Installation Guidelines

Mount the transducer perpendicular to the liquid surface.
Avoid mounting too close to the tank wall to prevent false echoes.
Position away from inlets and ensure the transducer points to the tank outlet.
Use a guide tube with a vent hole to prevent false echoes from turbulence and foam.

E-mail: [email protected] B = Blanking distance D =Distance from transducer to material surface L = Height in silo The distance D is determined from the velocity of sound and the time period t by the formula: D = V*T /2 Example: With the velocity of sound = 334.1 M/s, a time period of 60m/s corresponds to a transmission path of 20.046M and thus to a distance of 10.023M. An integrated temperature sensor detects the temperature in the vessel and compensates the influence of temperature on the signal running time.

E-mail: [email protected] Installation The transducer should not be mounted too close to the tank wall, the build-up on the tank wall cause false echoes. Keep transducer perpendicular to liquid. When you mount the transducer on the solid tank, the transducer must point to the tank outlet. Mount the transducer away from the inlet to avoid false echoes. The transducer should not be mounted too close to the tank wall, the bracket can cause strong false echoes. As is illustrated by the figure on the right, the transducer should be mounted on the top of guide tube to prevent the false echoes from turbulence...
