SPOHR-vertically recording water level gage recorder QP1

The automatical gage recorder QP1 was developped as replacement for the approved SPOHR level no. 212, which has been used in many cases for decades to the full satisfaction of its users. Besides of the use of modern materials and technologies essential value was set again on a user-friendly construction with high accuracy and reliability.
The recorder possesses an electronically switchable, quartz-controlled drum engine and a two-cell housing of glasfibre strengthened polyester so that the device can be installed unprotected outside. Six different registration ranges and twelve various drum-speeds can be choosen.

Working method

The changes in water level are submitted over a cable with buoyancy chamber, balance weight and over wheels in selectable transmission ratio (registrating scale) on a pen. This pen records and scales down the water level changes in a diagram paper which rotates with the predefined speed. Therefore the exact water level changes can be read out chronologically.

Special advantages:

• The housing material glasfibre-strengthened polyester (proved and tested in boat building and for the construction for junction boxes) is weatherproof, has a low weight and a high stability.
• separated chambers for the registration device and floating tube protect the gage recorder from ascending humidity. Cause to the locking door at the back side of the gage (Picture 2) the floating tube is easily accessible. An air ventilation of the chambers prevent from the condensing of water.
• The optionally hot zinc-dipped mounting plate  available. With the mounting plate the gage can be easily mounted and easily vertically justified.
• The incapsulated step-controlling clockwork is an easy longlife construction for outdoor usage. The controlling of this clockwork in modern CMOS-technology is characterized by trouble-free starting-up, quarz-accuracy, low power consumption and reliableness. The drum engine speed can be easily selected by a turn-switch (picture 3) and therefore be adjusted to the required recording accuracy. The power consuption decreases with increasing time of circulation. With the display for the battery-control the actual state of the battery can be controlled easily.
• The six different registration ranges can be easily adjusted by reallocation of the floating cable and change of the plastic-gearwheel.
• An accurate construction of all constructive details guarantees highest accuracy, smooth running and error-free registration.
