Water Level Submersible stainless steel pressure transmitters, ideal for measuring hydrostatic water level in boreholes, reservoirs, and water storage tanks, that can also interface with controllers or PLCs.
Boreholes
A borehole is a narrow shaft bored in the ground, which when used as a water well has a vertical pipe (casing) and well screen installed to to keep it from caving, helps prevent surface contaminants from entering the borehole and protects any installed pump from drawing in sand and sediment.
For the pumps to work efficiently they must maintain a level of water above them to stop them running dry which can destroy the pump in a very short period of time.
Furthermore, as the need to manage water supply demands from agricultural, industrial, environmental and domestic users grows, groundwater level monitoring has become increasingly important.
Our range of hydrostatic pressure transmitters can be used in these applications for reliable continuous water level monitoring and control with good accuracy and long term stability.
3400 series
Performance
- High stability and repeatability
- All stainless steel housing
- Resistant to high voltage surges
- 4-20mA two-wire output
- Zero and span adjustment on-site
- Ranges 0-5mWG to 0-500mWG (0-16ftH2O to 0-1,640ftH2O)
- Pressure tight cable sheath for trouble-free venting
- Ø 40mm (1.6″)
- *Intrinsically safe option. Flammable gases (zone 0) and dusts (zone 20)
Advantages
The 3400 submersible depth and level transmitter has been designed for the accurate measurement of the depth and level of fluids. Standard version has output signal of 4-20mA, two wire. Options include; outputs of 0-5Vdc and 0-10Vdc, remote amplifier for surface adjustment of zero and span.
For submersion in aggressive or corrosive liquids the 3400 is available in specialist materials such as Inconel 625, Hastalloy C, titanium and plastic. The standard depth transmitter is fitted with a nylon nose cone to prevent sludge build-up. The nose cone connection may be replaced by a variety of threaded process connections common in sub-sea requirements. We have many options available for high pressure and hydraulic sub-sea applications. Standard applications include reservoir and borehole level monitoring, water mains pressure metering, power level and outlet pressure on submersible pumps. Electrical connection is via a screened cable protected by a tough nylon pressure tight sheath, which allows excellent trouble-free venting to the surface.
Applications
Standard applications include reservoir and borehole level monitoring, water mains pressure metering, power level and outlet pressure on submersible pumps. Other available options include high pressure and hydraulic sub-sea applications.
