data logger parshall flume ultrasonic open channel flow meter

Short Description:

The series is a remote version ultrasonic open channel flow meter (UOC). It consists of two elements, a wall mounted host, which has a display and an integral keypad for programming, and a probe, which must be mounted directly above the surface to be monitored. Both of the host and the probe are plastic leak-proof structure.
It can be widely applied to the environmental protection, water treatment, irrigation, chemical, and other industries.

Features

The series UOC is capable of the following functions:

High detection accuracy, the flow meter measurement changes with 1mm, the accuracy of change in level is 1 mm;

Suitable for a variety of weirs and flumes, Parshall flumes (ISO), V-Notch weirs, rectangular weirs (With or Without End Contractions) and custom Formula type weir;

5-inch anti-interference ultra-high-definition color touch screen, stable work, not afraid of oily water stains; Modern display effect

Displays flow rate in L/S, M3/h or M3/min;

Support displaying trend curves and historical records (Can be exported through mirco SD card)

The setting interface is password protected

AC and DC two-way power supply design, can be connected to AC or DC power supply.

Super-capacitor powered clock design, no need to replace the built-in battery for life

Excellent anti-interference capability;

The cable length between probe and host up to 1000m;

The probe with leak-proof structure and IP68 protect grade;

Chemically resistant probe materials for maximum application flexibility;

Provided 4-20mA output and RS485 serial communication (MODBUS-RTU) output;

Provided programmable 5 relaysat most for alarms;
