Instrumentation for water and wastewater
Flow meters, level meters and pressure sensors, matched to the process
Each record starts with the measuring principle, the limits it works within, and the output your control system expects.
- Flow: electromagnetic, ultrasonic, Doppler, turbine
- Level: radar, ultrasonic, hydrostatic, sludge blanket
- Pressure: transmitters, controllers, switches
What we measure
Four families, chosen by principle
Grouped by what is being measured; each family holds the principles inside it and the media they suit.
Catalogue
Instruments plants specify most
Two from flow, two from level and two from pressure, with the one line an engineer reads first.
AM-ULF-H Handheld Ultrasonic Flow Meter
Handheld clamp-on ultrasonic flow meter for DN15–DN6000: ±1 % of reading, 2000-line logger, RS-232, over 12 hours per charge.
AM-ULF-P Portable Ultrasonic Flow Meter
Portable clamp-on ultrasonic flow meter for DN15–DN6000: 20-hour battery, built-in thermal printer, ±1 % of reading, RS485.
AM-P201 Submersible Level Transmitter with LCD Display
Submersible level transmitter with a local LCD display — the P200 series: 0–200 m, 0.2/0.5 % FS, RS485 and 4–20 mA, IP68.
AM-ULM-D Ultrasonic Level Differential Meter
Two-probe ultrasonic differential level meter: 0–25 m difference range, ±0.5 %, two relays, 90–240 V AC or 12–24 V DC, 4–20 mA and Modbus.
AM-P100 Pressure Sensor
Diffused-silicon pressure transmitter, −0.1 to 100 MPa at 0.25 % FS, 316L diaphragm, 4–20 mA or RS485, IP65.
AM-P104 Digital Pressure Controller
Digital pressure controller for pump start-stop and alarm logic, with two relays and a retransmitted 4-20 mA signal.
Applications
Application packages
One measuring point, solved end to end: the conditions that decide the principle, the instruments, and the scope of supply.
Water Distribution District Metering
District metering and pressure management for distribution networks, where night flow and peak demand differ by an order of magnitude.
Sludge Transfer and Blanket Level
Sludge transfer flow and blanket level in settling tanks, where coating and low velocity defeat clean-liquid instruments.
Industrial Process Measurement
Flow, level and water quality in chemical, food and pharmaceutical processes, where wetted materials and signal compatibility decide the choice.
How a point gets solved
From process data to a calibrated instrument
Three steps, in the order they decide the outcome.
-
Send the process data
Medium, pipe or channel geometry, temperature, pressure, conductivity, solids and the output the control system expects.
-
We choose the principle
The application package names the principle the process calls for, and the conditions under which another one is the better answer.
-
Configuration, calibration, delivery
Range, wetted material, output and mounting are fixed, the supplied configuration is written down, and the instrument travels with its datasheet.
Field notes
What decides a measurement in practice
The conditions, the failures they cause, and the checks that catch them.
The calibration interval nobody budgets for
Instrument price is the smallest part of the number that matters: consumables, access and verification decide the second-year cost.
What the pipe wall takes away from a clamp-on ultrasonic reading
Couplant, straight run and mounting position cost a clamp-on ultrasonic more accuracy than the electronics ever do.
Why an electromagnetic flow meter reads zero on a plastic pipe
A zero reading on a plastic pipe is almost always a grounding problem, not a meter problem. Here is how to tell the difference.
Documentation
Datasheets and manuals
The file behind each record, with its format and size, so you know what you are opening.
