First, the input level meter Product Overview
ZRN701A input type level gauge. Input type liquid level sensor , Level Transmitter , Water level gauges Imported oil-filled silicon, stainless steel full seal welded structure design, with good moisture resistance and strong media compatibility, can be used in many industrial applications less corrosive medium; key components of circuit sections, pressure-sensitive core , the choice of international brands of components using international production standards process, so that the technical indicators have reached international standards, the product has good stability and high accuracy.
Second, the input level meter Applications
Widely used in water plants, sewage treatment plants, urban water supply, high-rise pools, wells, mines, industrial pools, water tanks, oil tanks, hydrogeology, reservoirs, rivers, oceans and other places

Installation:

When measuring the static level in an open container, the level transmitter directly into the bottom of the container, the container opening adjustable nylon tape or the like tripod mount cable (junction box) can be fixed in when the flow of liquid level measurement, due to fluctuations in the larger media, you can insert a Φ45mm pipe in the liquid, while playing several holes on the back wall of the flow direction at different heights, so that the liquid flows into the pipe. Another method is to install damping means in the bottom of the liquid to filter sediment and eliminate the effects of dynamic pressure and waves on the measurement.

Order details:

· Specify the measurement range (level height), for some special media, indicate medium density.

· The selection, should pay attention to the measured medium in contact with the product compatible material, for special media, can be customized.

* Product installed in more thunderstorms region, the order should specify the 'mine', it recommends that users install lightning protection devices field, and make sure that products and power ground.

• For air conductivity cable length selection: generally higher than the actual level of 1 to 2 meters height length.
