34 Water/Wastewater New Simple to Use Pump Control Unit for Groundwater Sampling
Solinst (Canada) unveils their newly designed Model 464 Electronic Pump Control Unit.e Model 464 Electronic Control Unit is made to work easily with pneumatic pumps and obtain representative groundwater samples during monitoring programs such as site assessments, contaminant detection, site characterizations, remediation projects, compliance monitoring, etc.
The Model 464 is designed to help field technicians meet the sampling protocols of regulators worldwide, including the U.S. EPA. The Controller allows faster purge rates, as well as precise low flow control to ensure a representative sample at 100 ml/min or less when sampling for Volatile Organic Compounds (VOCs).
The Control Unit outputs 125 psi and runs on 4 AA alkaline batteries that can last up to 100 hours of normal use. The Model 464 also has a manual mode that allows users to operate the Control Unit without batteries, using only a compressed air source.
These convenient boxes are rugged, dependable and suitable for all environments. Tubing is supplied and quick-connect fittings allow instant attachment to pumps, dedicated pump well caps, portable pump reel units and to an air compressor or compressed gas source.
The Control Unit is excellent to use with the company’s own Model 407 Integra™ Bladder Pumps and Model 408 Double Valve Pumps. The Model 464 Electronic Pump Control Unit is now available for purchase, for more information, visit:

Ultrameter II With all new features and functions …
The Ultrameter II still delivers the most accurate dissolved solids measurements of any instrumentation and the greatest degree of accuracy available for pH, ORP and Temperature measurements, but has been redesigned to include an LSI/Hardness Calculator, Free Chlorine Measurements and Bluetooth® data transfer with the optional bluDock™ accessory.
The LSI calculator makes it easy to analyse the scaling nature of water in the lab or in the field. The calculator computes the saturation index of a sample based on measured and inferred values for pH, temperature, hardness and alkalinity. You can then change any of these values in user adjust mode to analyse the effect of the change on water balance. User mode also allows you to input measured values for alkalinity and hardness as determined by other independent testing for a precise saturation index value.
Within the LSI Calculator is a Hardness calculator that allows you to select either ppm or grains of hardness units.
Free chlorine measurements are mathematically derived from Oxidation Reduction Potential measurements. The mV to ppm free chlorine conversion algorithm is based on a published conversion curve and bench testing performed at the Myron L Company. With this new feature Myron L instruments can measure a dynamic range of sanitiser concentrations that is wider than the range of a colorimetric test kit.
With the bluDock™ accessory package, the Ultrameter II can now also transfer data wirelessly using Bluetooth® technology.
The Ultrameter II also features KCl, NaCl, 442™ and User-defined solution modes for proper solution modelling in diverse applications. Autoranging allows instrument to maintain resolution for solutions with widely varying concentrations. The pH/ORP sensor is user replaceable and can be calibrated to 1, 2 or 3 points depending on requirements. 4-wire conductivity cell construction, extremely stable circuitry and proprietary conversion algorithms deliver reliable repeatable results.
Ultrameter II is compact, portable, waterproof and buoyant, easy to calibrate and easy to use. Call the Myron L Company today to see why customers are saying this is the instrument they've been waiting for.

The Waterpilot FMX21 level sensor from Endress+Hauser (Germany) has a stainless steel housing and an easy-to-clean, flush- mounted process diaphragm, making it ideal for measuring the level of sludge and wastewater. With an optional Pt 100 sensor, it can also measure temperature. A corrosion-resistant, coated version is available for use in particularly aggressive environments, such as salt water.
The FMX21 uses a ceramic cell to measure pressure. Any changes in pressure cause a change in capacitance, which the sensor’s electronics convert into a 4-20mA signal that is linear to the level of the liquid. HART 6.0 is superimposed on the 4-20mA signal, allowing an operator to adjust the range remotely.

VERSATILITY. The most accurate, reliable, simple-to-use water quality analysis instrument just got better. The Ultrameter II 6Psi now includes an LSI/Hardness calculator and bluDock™ wireless data transfer (optional). Visit us at
www.myronl.com to learn more.
The sensor is ideal for sludge because the ceramic cell withstands corrosion better than any other material. Cleaning is very easy, without losing calibration, a characteristic of ceramic diaphragms. Applications include lift stations, thickeners, digesters and sludge holding tanks.
For water and wastewater applications,
it has KTW, NSW and ACS drinking water approvals. A wide range of accessories make it easy to implement complete measuring point solutions in a water plant. By using the Field Xpert PDA, operators can communicate to the FMX21 wirelessly, to set all parameters and diagnose problems.
