OTT RLS radar level gauge product features robust and efficient design of radar technology: OTT RLS (radar level gauge) is a surface water level measurements for non-contact radar level gauge, which uses pulsed radar technology for liquid position measurement, this energy-saving, non-contact measurement techniques such OTT RLS without temperature gradient in the measurement, and the effects of pollutants in water of the precipitate, which can obtain accurate measurement results. Easy to install: OTT RLS is transmitted to the surface by radar pulses to measure, so that he can be mounted vertically above the water, such as: a bridge or other auxiliary buildings, its rugged, lightweight and waterproof shell so that it fits together Very simple, because universal connectivity equipment (universal hanger), so the probe can be aligned very easy, even on uneven in places where it is very convenient. Measuring principle: OTT RLS using energy pulse radar technology to measure level, as shown in front splint smooth launch and receive antennas transmit antennas at each measurement radar pulses to the surface after the pulse signal is reflected in the water time (delay time) receiving antenna detects, (www.njflmt.com) pyrometer to the surface from the transmitter to the receiver the reflected pulse signal depends on the distance the water with OTT RLS, OTT RLS is the use of the delay time with the distance to the surface to achieve a linear relationship between the level (distance value) of the measurement. Fluctuation compensation: OTT RLS achieved independent measurements at approximately 16 times per second, after the completion of a measurement cycle and outputs the result obtained by calculating the average value as, by calculating the average of the fluctuations of the measurement results is minimized, such Measurement results can be comparable to the value of the hydrostatic level measurement wells. Simple and reliable start setting compact, lightweight construction - weighs only 2.1kg; easy gimbal rotation - easy to align the front plywood (with antenna side); away from the surface of the sensor, making installation more secure; use mathematical methods to compensate fluctuations affect the measurement results, without changing its own structure; [simple] standardized system integrated communication protocols, and transmission data can (SDI-12, RS-485 between data recorders or other devices, and outreach 4-20mA current signal output); low power consumption - can be used in remote areas; RS-485 interface - Allows connection cable lengths up to 1000 m, which makes data recorder and the power supply system away from the sensor; wide voltage input: 9.6-28V (typical range: 12-24V) - allows the use of solar cells, batteries and delete reliable grid voltage instability and other powered devices operating non-contact measurement - ideal for measuring the flood; sensor not placed water - so hydrological measurements do not have an impact on its environment; smooth antenna means infested insects and spiders will not be a problem - they do not cause damage to the measurement results; compact and rugged design - longer sensor life but at the same time minimizing the amount of maintenance; structural design using the diving bell principle; unobtrusive design - unobtrusive, making the chances of reducing vandalism Technical Parameters Measuring range level measurement ??? ?????? ?????????????????????? 0.8-35 m ??? measurement accuracy ??????????????????? ?????? ??? ± 3mm ??? ????? ??????????????????????? measurement time 20 seconds (SDI 12) or 30 seconds (4-20Ma) ??? antenna beam angle (wideband) ????????? ??????? 12 ° ??? ??? ??? supply range of electrical parameters? ??????????????????????????? 9.6-28V DC, typical: 12-24V DC ??? measuring power consumption ???? ?????????????????? ?? <149mV (<12mA at 12V when) ??? non-measurement state power ???????????? ???? ???? <1mV (<0.05mA at 12V time) communication interface ??????????????????????????? ??? ? 4-20mA, SDI-12, RS-485, two-wire (SDI-12 protocol)? ??? ??? size and weight dimensions L × W × H ???????????? ??????? ?? 222mm × 152mm × 190mm ??? weight (with bogies) ???????????????? ???? about 2.1kg? ???
