V1.0 September 2017

 

 

It is VITAL that personnel responsible for the installation and 

use of the piezometers READ and UNDERSTAND the manual, 

prior to working with the equipment.

 

  

**********

 

As stated before, it is vital to check all the equipment in the shipment soon after 

taking delivery and well before installation is to be carried out.  Check that all 

components that are detailed on the shipping documents are included.

INSTALLATION

 

 

This section of the manual is intended for all installers of 

Geosense

®

  

IPI

’

s and is 

intended to provide guidance with respect to their installation.

 

 

It must be remembered that no two installations will be the same and it is inevitable 

that some 

‘

fine tuning

’ 

of the following procedures will be required to suit specific site 

conditions.

 

5.1

 

Preparation for Installation

 

IPI

’

s are designed to be installed within specialist inclinometer casing. The casing 

must be either installed in a borehole of fixed firmly to a structure.  Prior to installation 

of an IPI, it is essential to establish and confirm details of the installation to be carried 

out.  Some of the main considerations are listed below :

- 

1.

 

Intended elevation and length of each IPI element

 

An IPI comprises a series of interconnected elements.  The uppermost wheel 

set must be located a minimum of 250mm from the top of the inclinometer 

casing so as to accommodate the support and cable connection components.  

This distance can be varied by adjusting the length of the wire hanger extension 

(stainless steel rope).

 

 

The IPI probes are the measuring elements and the separation between the IPI 

probes (referred to as the 

‘

Gauge Length) is maintained by extension rods.  

Standard extension rods are available to provide 1, 2 and 3 metre gauge 

lengths and the gauge lengths can vary within a single installation.  

 

 

For example; an IPI installed in an inclinometer casing in a landslip might use 

3m gauge lengths in its upper zone (within the slip body) and 1m gauge lengths 

in the slip zone.

 

2.

 

Directional Orientation

 

The primary measuring axis of the IPI is A+ / A

-

 which is the same orientation as 

the wheels.  The A+ direction corresponds to the direction of the 

FIXED WHEEL 

and, consequently, A 

-

 is in the direction of the 

SPRUNG WHEEL

.
