KLD804 High Sensitivity Wireless Radar Level Transmitter With Low Current Consumption

KLD804 80G FM Radar Level Sensor

Introduction
In the process of industrial automation control, material level is an important parameter. There are many methods of material level measurement. For different working conditions and media, material level gauges with different measurement principles can be used for measurement, such as static pressure type, float type, heavy hammer type, ultrasonic and other common material level measurement methods. Instruments have their own characteristics and application ranges. Radar level gauge uses advanced radar pulse wave measurement technology, with its excellent performance, especially in tanks with agitation, high temperature, large steam, strong dust, strong medium corrosion, easy scarring and other harsh measurement conditions It shows its excellent performance and plays an important role in industrial automation production.

Wireless Radar System Solutions:
In the production process of petrochemical, coal, cement, metallurgy and other industries, in order to ensure the safety of liquid during storage, real-time monitoring of pressure, liquid level, temperature, humidity and gas concentration on the liquid surface in the storage tank, etc. How to collect and transmit the relevant parameters of the liquid stored in the storage tank to the remote control center, and how to initiate emergency measures in case of emergency has always troubled the management personnel. Traditional storage tank monitoring mainly relies on periodic inspections by personnel on duty. The labor cost is high, and many human factors will be left behind, posing safety risks. Based on 433MHZ radio frequency, wireless data transmission solution of GPRS mobile communication, real-time remote monitoring for the pressure, liquid level, temperature, humidity of the storage tank, gas concentration on the liquid surface, and other parameters that the user cares about, and in case of emergency activate the corresponding emergency facilities.

Feature

It can realize wireless networking within 20 kilometers.
The integrated 433M wireless high-frequency radar adopts the most advanced 433M wireless radio frequency transmission technology in the industry. Its maximum transmission distance is 20Km, and it is powered by solar panels or 220V mains. Complicated processes such as on-site wiring are omitted. The radar outputs RS485 digital signal and adopts Modbus bus protocol to realize wireless networking within 100 units. The wireless transmission part adopts LoRa remote modem technology, which has excellent anti-interference ability and can minimize current consumption. High sensitivity and military circuit design make its link budget reach the leading level in the industry, making it the best choice for long-distance transmission and applications with high reliability requirements. Compared with the traditional GPRS transmission method, its cost is greatly reduced. Not limited by the mobile communication network, the reliability and anti-interference ability are greatly improved.

Installation Method

Flange Installation

When using flange installation, the minimum distance between the instrument and the tank wall should be 200mm.

• datum plane
• vessel center or axis of symmetry

Hoisting Installation

Note: Please avoid vibration, strong electromagnetic interference and loads during installation.

Misalignment method:
1. On-line calibration: on-site process equipment needs to stop production;
2. Reference point calibration: full scale setting;
3. Upper computer calibration: 250Ω resistor, Hart converter, USB interface are required.
