DS15 Flow Indicator, Switch, Transmitter
F.S. Flow Ranges from 24 lph to 50,000 lph Water
DESCRIPTION
The model DS15 flow meters work according to the proven variable area principle. The float is moved upward in a tapered tube by the flowing medium and its upper edge indicates the flow rate by means of a scale affixed on to the measuring tube.
By using a float with an integrated magnet, optional alarm contacts or an analog output transducer may be added.
All flow meters have a male thread on the measuring tube and are supplied with two schedule 80 PVC-U pipe couplings. Please call for coupling materials other than PVC .
The variety of materials used and the simple to exchange measuring scales make these meters universally suitable for most liquid and gaseous media.
Applications are in the water treatment industry, wastewater, plating and surface finishing, chemical and food industries and many more.

SPECIFICATIONS
Measuring Tube Material - PVC-U transparent, Polyamide, Polysulfone
or PVDF (for use with alarm contacts or analog output
transducer only)
Float Material - PVDF, optionally st. steel AISI 304 and PVDF with
integrated magnet
O-Rings - EPDM, Viton optional
Pipe Connections - PVC, optionally PP, PVDF
Max Pressure - 10 bar @ 20°C
Max Temperature Flow Tube Only -
PVC: 60°C
Polyamide: 75°C
Polysulfone: 100°C
PVDF: 110°C
Max Temperature with connectors made of:
PVC: 60°C
PP: 80°C Max
PVDF:110°C
Mounting Position - vertically, flow from bottom to top
Mounting - with straight pipe, 5-7 x pipe dia. upstream and
downstream of meter F
Measuring Accuracy - ±4% F.S.
Scales - water scales (in LPH) and air scales (in m^(3)/h) referenced
to 0, 1, 2, or 3 bar above atmosphere and 20°C are standard.
For other media, i.e. gases with higher pressures, HCL (30%),
NaOH (30%) as well as other units of measurement
(m^(3)/h, l/sec, GPM) special scales can be supplied.
Accessories
Alarm Contacts - bistable, N/C or N/O contact function on rising flow
Mounting: adjustable on measuring tube
Contact Rating: Max 220 VAC, 0.5A Max 10A/10VA
Operating Temperature: 0...+55°C
Hysteresis: 3 mm of float height
Electrical Connection: Two wire, independent of polarity
Analog & RS-232 output -
The optional analog output transducer is mounted onto the
measuring tube of the DS15 flowmeter and registers the height of
the float by means of an analog Hall sensor. The integrated
electronics converts this signal to a 4-20 mA output. Additionally a
digital value is available via an RS-232 interface.
To utilize the analog output transducer, the standard float must
be exchanged for a float with an integral magnet.
The transducer is equipped with an EPROM which is programmed
especially for the application. Therefore it is not possible to
field adjust the transducers without consulting the manufacturer.
Electrical connection: 6-pin plug per DIN 45322 (included) |
