| The Model 615 Piezometer has a stainless steel, 50 mesh
cylindrical filter-screen, within a 3/4" (20 mm) stainless steel
drive-point body, screen support and a barbed fitting for
attachment of sample tubing. Optional heavy-duty extension
couplings are also available to create a strengthened and more
rugged piezometer.
The inner barbed fitting allows connection of 5/8" OD
x 1/2" ID (16 mm x 12 mm) LDPE or Teflon sample tubing.
This prevents sample water from contacting the steel
extension rods, and maintains high sample integrity, even
when inexpensive carbon steel extensions are used.
Ideal for soil vapor sampling. Where an air-tight connection is
most desirable, the compression fitting option allows users to
attach 1/4" (6 mm) sample tubing directly to the top of the
screened portion of the drive-point.
The 615 S shielded drive-point has a single use, 1-1/2" (38 mm) dia. shield to avoid smearing and plugging of the
screen during installation. The strengthened connector at the
top of the drive-point acts as an annular seal, which avoids
contamination from higher levels in the hole.
The 615 N, designed without a tubing barb, is to be used for
water level measurements. This saves money and provides
better access for Water Level Meters. |
 Installing Piezometers with a
Manual Slide Hammer |
| Direct push sampling has quickly become
a popular way to obtain groundwater
samples. However, sampling within drivepoints
requires a narrow diameter
sampler. Solinst offers several options for
this specific sampling application. |
| Peristaltic Pump, Model 410 |
| The Peristaltic Pump uses the suction lift
principle. Suitable for 1/4" (6 mm) ID
or larger diameters. The Peristaltic Pump
provides a regulated and steady flow.
It works effectively up to 33 ft. (10 m)
at sea level. |
| WaTerra Pump, Model 404 |
| The WaTerra Pump operates as an
inertial pump. A check valve and
tubing, is raised and lowered to lift a
sample. The SS10 foot valve suits wells
as narrow as 1/2" (12 mm) ID and
works to depths of 74 ft. (25 m). |
| Miniature Point Source
Bailer, Model 429 |
| The 1/2" (12 mm) dia. stainless
steel bailer works very well in the 615N.
The bottom emptying device permits a
regulated, steady flow. |
| Hydraulic Head |
| Water levels can be measured in any of
the drive-points described, using a
Solinst Model 102, or the Narrow Tape
Solinst Model 101 or 101M Water
Level Meter for the most accurate
hydraulic head measurements. |
| Manual Slide Hammer |
| For the most inexpensive wellpoint
installations, the Manual Slide Hammer
can be used to install the Solinst Drive-
Point Piezometers. The 25lb (11Kg)
slide hammer and all other equipment
can easily be transported in a car or
truck to most sites.
A heavy duty drive head is used, on
which the slide hammer impacts, and a
tubing by-pass ensures that the tubing
does not get damaged during installation. |
| Couplings |
| Heavy duty couplings are available for the
Model 615 Drive-Point Piezometers. The
reinforced shoulder gives added support
to the pipe threads, to withstand driving
stresses and to give more accurate alignment.
The maximum OD is 1.5" (38 mm). |
| Depth Limitations |
| Drive-point piezometers are not suitable
for all sites. The depth limitations vary,
especially with soil conditions and the
drive method used. |
