Welcome to buy ESM ultrasonic level meter!
ESMUL21, by 4 ~ 20mA connected to a display table or a variety of DCS systems, industrial automation operation, providing real-time level data is safe, clean, high precision, long life, stable and reliable, easy installation and maintenance features for acid, alkali, salt, anti-corrosion, high temperature and other areas.
1.Feature
1. Circuit Design from the power supply section on the selection of high-quality power from the module, component selection of imported high reliable device can replace the same type of imported instruments.
2. Patented sonic intelligence software for intelligent echo analysis, debugging, and without any other special steps, this technique has a dynamic thinking, dynamic analysis capabilities.
3. My company has patented sonic technology intelligence, greatly improving the accuracy of the instrument, level accuracy of ¡¾ 0.25%, resistant to all kinds of interference waves.
4. The instrument is a non-contact instrument, not in direct contact with the liquid, and therefore low failure rate. Instrumentation offers a variety of installation, the user can through this manual instrument calibration.
5.All input and output lines of the instrument have lightning protection, short ci

1.Installation method
Under the open environment in general use bracket installation, the instrument comes with a fixed flange. Pools or tanks cut a 60mm diameter hole in the mounting position, the probe into the instrument, and then tighten the flange bottom up. The installation must ensure that the probe surface and the measured liquid level meter.
2 meter installation guidelines
1) probe emission surface to the lowest level of the distance should be less than the purchase range of the instrument.
2) the probe to the highest level of emission surface distance should be greater than the optional instrument blind.
3) emission surface of the probe should be parallel to the surface of the liquid.
4) installation position of the probe should avoid directly below the inlet and discharge port of the location and other liquid volatility.
5) If the wall or the tank wall is not smooth, the need to mount the instrument away from the wall or the tank wall above 0.5m.
6) If probes emitting surface to the highest level is less than the distance meter to buy blind, need to install an extension tube, extension tube diameter
Greater than 120mm, length 0.45m ~ 0.60m, mounted vertically, smooth wall, tank openings should be greater than the extension tube
path. Or through the tube to the bottom of the tank, diameter greater than 100mm, tube holding the bottom left hole extending inner tube surface and contour tank.
3 Installation Considerations
1) meter installation is recommended to install the outdoor sun visor to extend the life of the instrument.
2) wire, cable protection pipes, pay attention to sealing to prevent water.
3) While the instrument itself with lightning protection devices, but the instrument in a multi-mine area, it is recommended in the instrument into the outlet end of the additional Install a dedicated lightning protection devices.
4) instrument in particularly hot, cold places, that the ambient temperature may exceed the job requirements of the instrument, it is recommended around the level meter plus high fortification, low temperature devices.
