孟加拉采购需求：差压变送器，差压传感器，工业液位变送器，工业液位传感器，低价液位变送器，温度传感器

I am looking for a quotation for two types of magnetic liquid level instruments. The first one is a magnetic liquid level switch with a transmitter, suitable for specific flange sizes and pressure ratings. It has a notable measurement range, operates under a certain pressure, and requires a 24V DC power supply, with an output signal range of 4-20 mA. The expected density of the material it will measure is 1.00 g/cm3. The second item is a magnetic liquid level gauge, also equipped with a transmitter, compatible with different flange dimensions and pressure specifications. This device has its own measurement range and shares the same power and output signal requirements. I would appreciate it if you could provide your best price for these items. Thank you!
