Lightning liquid water/fuel level sensor price

Description

HM21F lightning liquid level transducer measures the liquid level using the principle that the liquid static pressure is directly proportion to the liquid height. This series of product is specially designed for the thundering areas in the Southern China using advanced silicon piezoresistive sensitive element made by German HELM Company, supported with HELM–patent lightning device. It is suitable for hydrographic and water conservancy liquid level measurement in the river, lake, and reservoir. It has successfully been applied in many hydrographic industries.

Tips of Selection

The medium to be measured shall be compatible with the material contacting with the product. Meanwhile, it is needed to be indicated with density of the medium to be measured under the measuring status (except for water).
Please indicate when placing an order in case of battery power supplying.
The F1, F2, and F0 shown as the additional functions are only suitable for split–type liquid level transducer and inserted–type liquid level transducer.
The code E, an additional functional code for selection, and intrinsically safe explosion-proof Ex ia II CT5 must be power supplied via safety barrier.
The length of cable shall be L = X m + 1m. Please indicate for extension when placing an order. There are two kinds of cable material. The polyurethane is more flexible with good wear resistance, which may be selectively used. Under the condition without special indication, the PVC cables shall be supplied.
The corresponding relationship of 1m water column under standard condition ( i.e. 4℃, g = 9.80665 m / s2) shall be 1 mH2O = 0.1kgf / cm2 = 9.8kPa
Please contact us in case of the other special requirements and clearly indicate them when placing an order.
