Problems solved by technology

Because the sampling water is turbid surface water, or other turbid environmental protection water, the water contains sand and other sundries, the sand entering the measurement chamber 52 seriously affects the accuracy of the instrument measurement signal, and damages the measurement chamber 52 and the lower piston 40. Surface roughness, causing drift in the measurement signal

Embodiment 1

[0016] It works like this:

[0017] See Figure II : the present invention makes the measurement chamber base 64 increase the sand trap 66. When the sand grains in the sampling water enter the space 42 of the measurement chamber 52, they immediately fall into the sand grain trap 66, and stay in the trap 66 and cannot come out. This invention effectively avoids the impact of sand particles in the measurement water on the measurement signal, and protects the surface finish of the measurement chamber 52 and the lower piston 40 from being damaged. Sand particles are washed out of the trap 66 during cleaning of the probe.

[0018] The present invention enables the measurement chamber base 64 to serve two functions: (1) prevent sample water from flowing out of the measurement chamber 52; and (2) provide a sand trap.

Abstract

The invention relates to a novel design of a measurement chamber base of an online streaming potential sensor and in particular relates to an improvement of an online streaming potential measuring instrument, namely a sand trap added on a probe measurement chamber base. The probe base of the current online streaming potential sensor is improved (a base trap is added), so that sand entering the probe measurement chamber immediately drops into the base trap, and the influence of the sand on a measuring signal is eliminated. Meanwhile, the surface smoothness of the measurement chamber and the lower piston is prevented from being damaged.

Description

Technical field [0001] The present invention involves a new design of a mobile potential online sensor measuring room base, especially involving an online measuring instrument probe to measure the bottom of the driving potential to increase the sand trap technology.The surface of the piston surface is not damaged. Background technique [0002] The mobile potential online sensor is a real -time measurement device, and the sampling water continuously flows through the sensor probe (from the probe in the water outlet 14, from the outlet from the probe out of 10).Because sampling water is turbid surface water, or other turbid environmental water, water contains debris such as sand grains, and the sand grains in the measuring room 52 seriously affect the accuracy of the measurement signal of the instrument, and damage the measurement room 52 and the piston 40.The surface is smooth, causing the measurement signal to drift.Currently traveling potential online sensor measurement room bas...
